In the early moments of the big bang, two elements were forged: hydrogen and helium. Technically, the tiniest traces of light elements such as lithium were produced as well, but nothing of consequence. The early universe was about three parts hydrogen to one part helium. All the heavier elements, from the oxygen in your lungs to the iron in your blood, were created through astrophysical processes—fused in stars…
A new study reveals that neutrino flavors could play a decisive role in the fate of massive stars, dictating whether they erupt into a supernova or collapse directly into a black hole.
Combining cold dark matter simulations with observations of stellar streams and globular clusters, researchers inferred a declining power-law initial mass function for globular clusters.
A new study reveals that the Chandrasekhar limit setting the upper mass bound for white dwarfs is not absolute. Highly magnetized white dwarfs might overcome this threshold.
Astronomers from the University of Warwick examined 151 white dwarfs situated approximately 65 light-years from Earth. Detailed spectral analyses reveal unexpected optical and atmospheric properties in these stellar remnants.
