The star that should not exist
At the centre of this picture is a very unremarkable looking faint star, too faint to be seen through all but the largest amateur telescopes. This ancient star, in the constellation of Leo (The Lion), is called SDSS J102915+172927 and has been found to have the lowest amount of elements heavier than helium of all stars yet studied. It has a mass smaller than that of the Sun and is probably more than 13 billion years old. Credit: ESO/Digitized Sky Survey 2
(PhysOrg.com) -- A team of European astronomers has used ESOs Very Large Telescope (VLT) to track down a star in the Milky Way that many thought was impossible. They discovered that this star is composed almost entirely of hydrogen and helium, with only remarkably small amounts of other chemical elements in it. This intriguing composition places it in the "forbidden zone" of a widely accepted theory of star formation, meaning that it should never have come into existence in the first place. The results will appear in the 1 September 2011 issue of the journal Nature.
A faint star in the constellation of Leo (The Lion), called SDSS J102915+172927, has been found to have the lowest amount of elements heavier than helium (what astronomers call metals) of all stars yet studied. It has a mass smaller than that of the Sun and is probably more than 13 billion years old.
A widely accepted theory predicts that stars like this, with low mass and extremely low quantities of metals, shouldnt exist because the clouds of material from which they formed could never have condensed, said Elisabetta Caffau (Zentrum fur Astronomie der Universität Heidelberg, Germany and Observatoire de Paris, France), lead author of the paper. It was surprising to find, for the first time, a star in this forbidden zone, and it means we may have to revisit some of the star formation models.
The team analysed the properties of the star using the X-shooter and UVES instruments on the VLT. This allowed them to measure how abundant the various chemical elements were in the star. They found that the proportion of metals in SDSS J102915+172927 is more than 20 000 times smaller than that of the Sun.

The star is faint, and so metal-poor that we could only detect the signature of one element heavier than helium calcium in our first observations, said Piercarlo Bonifacio (Observatoire de Paris, France), who supervised the project. We had to ask for additional telescope time from ESOs Director General to study the stars light in even more detail, and with a long exposure time, to try to find other metals.Cosmologists believe that the lightest chemical elements hydrogen and helium were created shortly after the Big Bang, together with some lithium, while almost all other elements were formed later in stars. Supernova explosions spread the stellar material into the interstellar medium, making it richer in metals. New stars form from this enriched medium so they have higher amounts of metals in their composition than the older stars. Therefore, the proportion of metals in a star tells us how old it is.
The star we have studied is extremely metal-poor, meaning it is very primitive. It could be one of the oldest stars ever found, adds Lorenzo Monaco (ESO, Chile), also involved in the study.
This picture shows the distribution of the light of different colours coming from the remarkable star SDSS J102915+172927 after it has been split up by the X-Shooter instrument on the ESO VLT. Different colours fall in different places in this strange picture and astronomers can use this data to find the chemical signals from different elements within the star, which show up as dark interruptions of the curved lines. The spectrum of the star appears to be triple at each wavelengths as it was split up using an integral field unit to collect as much light as possible. This ancient star has been found to have the lowest amount of elements heavier than helium of all stars yet studied. The only evidence of elements heavier than helium is two dark lines from the element calcium. Credit: ESO/E. Caffau
Also very surprising was the lack of lithium in SDSS J102915+172927. Such an old star should have a composition similar to that of the Universe shortly after the Big Bang, with a few more metals in it. But the team found that the proportion of lithium in the star was at least fifty times less than expected in the material produced by the Big Bang.It is a mystery how the lithium that formed just after the beginning of the Universe was destroyed in this star. Bonifacio added.
The researchers also point out that this freakish star is probably not unique. We have identified several more candidate stars that might have metal levels similar to, or even lower than, those in SDSS J102915+172927. We are now planning to observe them with the VLT to see if this is the case, concludes Caffau.

Look, if you have any confidence in the big bang theory, then you have to assume that star formation came about originally in a metal poor environment and that contradicting star formation models are wrong. So there's you're f%^&ing answer, a metal poor star.
This should be of considerable interest, but I don't understand the confusion - you kind of have to logically expect it if you believe in all the standard theories.

In fact Ive always wondered why, if we can see the big bang right now (or up to 300,000 years after the big bang) then we must be traveling away from that big bang at close to the speed of light otherwise the light would have caught up to us long ago and we would only see whatever is left where the initial big bang occurred and we would also see some weird ghost image of the stuff close to us that passed between us and the big bang while we were still traveling close to the speed of light away from the big bang.
I mean how is it possible that we can even see back that far and dont give me that speed of light bull because you know its a giant leap. Like they keep building bigger telescopes to see back further into the big bang well how can that light enter the receptor yet still be observable later?

To start with, according to Einstein the universe is not 13.7 Gigayears old in absolute terms. It is 13.7 Gyr just in terms of time measured in our reference frame. An observer in a different reference frame may measure it as just 1 year old, even if he is passing near earth at this moment.
Secondly, when you say that we are travelling at "near speed of light from the big bang" you are not taking into account that the space itself is expanding,( as measured by the red shift ), which has moved as to a much bigger distance from "BB remmanents" than our relative speed from them. In that sense we are far from being accelerated to relativistic speeds.

If the star really is that old - as it ought to be, given its mass - then it long predates the formation of the galaxy it's in. It's got to be a long, long way from the ancient star formation zone that gave it birth.
Was it a migrant, ejected from a long-ago galaxy and wandering the void, eventually scooped up by the Milky Way and sent into a regularized orbit?
Could it have brought planets with it on its voyage? Or accumulated some on the way?
In any event, I tend to agree with That Guy's point, if not his annoyed tone. If the star was formed 13 billion years ago, as this one appears to have done, then we shouldn't expect much metallic content. And we should expect that there is a star-formation route in that early hydrogen-helium-lithium environment. Since a method of formation in that environment isn't covered in the current theory of star formation, current theory needs work.
The low lithium level sure is perplexing.

The biggest surprise was that a population III (ie, the first gen) star could still be around. Most are hypothesized to be giants of several hundred solar masses which would burn through their fuel in much less than a billion years and then explode to seed the next gen of stars, but the article didn't mention the star's mass. The other surprise is the dearth of lithium in the star's spectra.

That comment is hard to follow, but we probably do know more about the cosmos than the bottom of our oceans. That's because the cosmos is more observationally accessible and the cosmological principle greatly simplifies the physical variations (unlike the hard to access micro and macro environments of the deep ocean).
The origin of the universe and the nature of reality (quantum mechanics) certainly are the biggest mysteries one can think of.

Because space expands. Think expansions like a man running away from a stationary source of sound. If he runs fast enough then the sound will reach him at a much later time than if he had stood still. This is why we can still see the remnants from the big bang from all over the place.
(At this point the analogy breaks down because since space expands every point once coincided with the place of the big bang and therefore we do not se the remnants of that event coming from one direction but from all directions)

Some thoughts about how such clouds could have condensed:
Any passing gravitatinoal influence (a galaxy, a black hole or merely a big, wandering star) could create enough of a disturbance in the gas cloud to create regions of high enoug denisty to start collapsing.

I predict these lone metal-poor stars will be found to be more rare. That this star remains smaller than the sun, and still so very old is also a bit difficult to explain? Need a mechanism to explain how this lithium is destroyed over time?

Hi Eth, hope that bet is just a beer. It doesn't have to be all that much less. Even at just 0.7 times one stellar mass a star's lifetime increases to around 20 billion years. No need to go to 0.4 Sol mass (red dwarfs).
A star's lifetime=mass/luminosity so for main-sequence stars you can use the formula (%solar mass)/(%solar mass)^3 × 10^10 years to calculate lifetime.

The authors posit that 1st gen giant stars might have been born in huge gas clouds that forged several stellar embryos rather than just one.
The infant stars in each cloud were closely spaced and their mutual gravity could kick the lowest mass embryo from the tightly packed group before that infant had a chance to grow into a massive, short lived star.
A few of these ejected, underweight stars could have survived to the present day if they managed to accumulate no more than the equivalent of 80% of the suns mass from their birth cloud.
The paper was criticized for making assumptions about how the early gas clouds behaved and for the length of their simulations, but perhaps given this discovery, they may be on to something.

The amount of elements heavier than helium at the top of the stellar atmosphere depends on the level of magnetic activity that separates elements in a star by mass like a plasma diffuser [1].
A 2004 survey of solar-like stars with little or no sunspot activity from magnetic fields protruding through the photosphere concluded:
"We thought we knew how to detect Maunder minimum stars, but we don't . . . our study shows that the vast majority of stars identified as Maunder minimum stars are well above the main sequence, which means they're not sun-like at all, but are either evolved stars or stars rich in metals like iron and nickel" [2].

Several posters here have questioned whether low mass Population III would have formed to begin with (if this star is indeed a representative of this class). Try searching for "low mass population III stars" to find some current research on such objects. Theoretical work over the last decade has uncovered several possible mechanisms for the formation of these early stars.
In theory a primordial 0.8 solar mass Pop III star should still be shining today, but what to look for?
A substantial body of work on low-mass Pop III stars focuses on how such stars may appear in the present day universe and how to discriminate between low mass Pop III stars and peculiar low mass Pop I and Pop II imposters. And for the record, the paper on this star does not ID it as a Pop III object, but it may turn out to be a candidate.

The videos may be the demise of the AGW and SSM scams, world leaders, and leaders of the scientific community that ignored empirical facts:
Earths unstable heat source, a pulsar, causes continuous climate change and continuous evolution of life Earth:

World leaders and leaders of the Western scientific community (the US NAS, the UKs RS, and the UNs IPCC) and editors of once-respected research journals (Nature, Science, PRS, PNAS, etc.) failed to condemn evidence of thirty years of data manipulation in Climategate documents and e-mails.

Re-posting the exact same paranoid fantasies based entirely on a desire to make reality go away is not helping you. It is simply more evidence that you are a Crank. And we didn't exactly need more since you are the Poster Boy on the site.
So how about you tell us where there is laboratory evidence that unbound neutrons have ever been seen to decay. Test after test of proton decay which should also detect neutron decay has never seen either.

It is an unusual star, the only one currently know with a very low metalicity ([Fe/H]=-5) that has essentially solar-like ratios of other heavy elements to Fe, where the other extremely metal-poor stars were relatively Carbon-rich.
Ultimately this is a discovery paper and the report of the discovery that this star was extremely metal-poor had to be reported first somewhere. The low (undetected, but consistent with a solar-like Fe:C ratio) carbon abundance challenges some existing low-mass star formation theories and this is why the first report appeared in "Nature".
The authors have identified nearly 2900 candidate, low-metal stars and examined 6 finding this one. No doubt they plan to examine more, and with this report, they and others are free to examine this one more as well.

I find it hard to believe you would pose such a question on a physics discussion group.
You could find the answer in any good textbook of physics or chemistry.
Or at any number of web sites:
1. www.particleadven...npe.html
"A neutron (udd) decays to a proton (uud), an electron, and an antineutrino. This is called neutron beta decay. (The term beta ray was used for electrons in nuclear decays because they didn't know they were electrons!)"
2. http://en.wikiped...on_decay
"In nuclear physics, neutron decay may refer to:
a. neutron emission by an atomic nucleus
b. free neutron decay
c. beta decay of a neutron inside an atomic nucleus
d. baryon decay as predicted by grand unified theories"

No. Not even even in physics book and definitely not in a chemistry book.
Which is NOT what I was asking. I am FULLY aware that UNBOUND neutrons decay. I asked about BOUND neutrons.
Which isn't actually the decay of a neutron it is the emission of one that will later decay if does not become bound again.>>

Which only occurs is in atoms with way too many neutrons. So many that a neutron will eventually be unbound. The pressure in a neutron star should prevent that as in that case ALL the neutrons will be right up against many neutrons. The Strong Force will be with them.
Undetected. And it was that lack of detection that I talking about. The lack of detection is a major problem for those GUTS. None of them fit the evidence at present due to that complete lack of decay.
That is the closest you have come to actually answering though. You have pretended that the question had never been asked for nearly two years now. This however is not an answer it is just another evasion.>>

I await the proof. Physical evidence for the first and math will do for the second since there is no way to get at a neutron star.

2. A "bound neutron" is part of the nucleus.
Decay occurs in both cases, as explained in the information provided.
You may have a comprehension problem. E.g.,

A neutron in a neutron star is not free either. AND neutrons in unstable nuclei are not really bound. That is why they decay. The Weak Force is just a higher order version of EM.
Or I may understand it better than you. Much more likely considering it has taken you TWO YEARS to reply to the question.
Gee two errors in one sentence. I am not angry and wasn't. I do not get angry online and ETHELRED is in no way the same as Ethel. Which I have pointed out to you before. I find that people that confuse the two tend to be misogynists.
True. Not in error either.
Whereas you can't even get my sex right. Not surprising for a bisexual child abuser.

Still it did get a response from Oliver. True he made more errors than I did but it was a response. Meaningless as it was since it still isn't what he needs to support his position.
He does indeed need evidence that BOUND neutrons decay. And that neutrons repel each other in a way that the Pauli Exclusion Principle does not cover, that is that they repel each other much more strongly and for a longer distance than the PEP requires. The latter is needed for him to claim that neutrons in a neutron star are not bound.

Yes. Neutron emission is one of the modes for spontaneous nuclear decays that transforms the nucleus. The others are electron emission (beta decay), positron emission, proton emission, alpha decay, and spontaneous fission.
I have read your papers before, and my question is this:
In your model for stellar energy production via neutron repulsion, which nuclei (or what are the general properties of the nuclei) are those that eject the neutrons that decay? It is not perfectly clear from your papers.
A related question (I think): you also refer to this equation rxn
--> n E
where E ~ 10-22 MeV. What are these "" which you refer to? Are they related to the neutrons in the nuclei that eject the neutrons? I am unfamiliar with this notation.
Many kind thanks in advance for your reply.

would be
(n) -- n plus E
and the item in quotes was a "bracket n bracket"
Let's see if this works...

Neutron stars [1] decay by:
a.) Neutron emission and
b.) Fragmentation (fission)
The lower limit on a neutron star is a single neutron.
Many ago (before you were born?) nuclear scientists tried to find a di-neutron.
Since 1971, experimental data that disagree with the Bilderberg model of the Sun [2] were avoided to protect the illusion that Earth's heat source is steady and in equilibrium [2].
That falsehood is the cornerstone of anthropogenic climate change story.
The Sun has evolved, Earth's climate has changed, both continue to evolve, as does life [3]

I regret that it took 40 years to figure out that the Bilderberg model of the Sun [2] and the AGW model of Earth's climate are two peas in the same propaganda pod.

Please clarify that since, as it is, it is quite beyond even the remotest concept of rational thinking.
Indeed it is right up there with you claim that the Sun has a rigid iron mantle that can be seen in Sun spots despite the photo you use as evidence does not have any signs of more than the expected trace of iron.

couldnt help but notice you completely ignored stellar_d's post and that when anyone asks you how bound neutrons decay you throw your arms up and cant think of anything other than "because it is".
