(Phys.org)—Astronomers have determined chemical abundances of several elements for six giant stars of a recently discovered stellar cluster known as Gaia1. The results, available in a paper published June 5 on arXiv.org, ...
(Phys.org)—An international team of astronomers led by Liliana Rivera Sandoval of the University of Amsterdam, Netherlands, has found 22 new cataclysmic variable stars in a globular cluster known as 47 Tucanae (47 Tuc for ...
Lomonosov Moscow State University scientists published the results of a study of unique ultra-slow pulsar XB091D. This neutron star is believed to have captured a companion only a million years ago, and since then, has been ...

European astronomers have recently studied the chemical composition of the low-mass globular cluster designated NGC 6362. Their detailed analysis of chemical abundances for 17 elements in the cluster provides important insights ...
When a star like our sun gets to be very old, after another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining, it will shrink to a fraction ...
