Tremendously bright pulsar may be one of many

Recently, a team of astronomers reported discovering a pulsating star that appears to shine with the energy of 10 million suns. The find, which was announced in Nature, is the brightest pulsar – a type of rotating neutron ...

Survivor of stellar collision is new type of pulsating star

A team of astronomers from the UK, Germany and Spain have observed the remnant of a stellar collision and discovered that its brightness varies in a way not seen before on this rare type of star. By analysing the patterns ...

Astronomers discover pulsations in crystalized, dying star

(Phys.org) —Astronomers from The University of Texas at Austin and colleagues have used the 2.1-meter Otto Struve Telescope at the university's McDonald Observatory to discover pulsations from the crystalized remnant of ...

Astronomers clash over the distance to the famed North Star

(Phys.org)—The North Star (Polaris) has played an important role in human history, yet knowledge of its fundamental parameters is unsatisfactory. That problem is attributable in large part to uncertainties tied to the star's ...

A New Class of Variable Stars Revealed

(PhysOrg.com) -- Modern astronomy sometimes makes discoveries by looking in new places, the distant universe for example, using telescopes and instruments that extend the previous limits of detection.

Brightness variations of sun-like stars: The mystery deepens

(PhysOrg.com) -- An extensive study made with ESO's Very Large Telescope deepens a long-standing mystery in the study of stars similar to the Sun. Unusual year-long variations in the brightness of about one third of all Sun-like ...

Stellar pulsations distribute key ingredient for life

As Carl Sagan famously said, "We're made of star stuff"—but how do stars distribute their essential "stuff" for life into space? NASA's telescope on an airplane, SOFIA, is finding some answers by watching pulsating stars ...

TESS first light on stellar physics

Using asteroseismic techniques, an international team searched for pulsations in a subsample of five thousand stars, from the 32 thousand observed in short cadence in the first two sectors (roughly the first two months of ...
