Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since ...

In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses. They definitely exist in East Lansing, Michigan.

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

Scientists found in 2020 that gravitational waves detected a year earlier came from two neutron stars — dense leftovers of exploded stars — paired up in a system 3.4 times the mass of the sun.

Aiming to resolve the "neutron star hyperon puzzle," the study of hyperon potential has emerged as a frontier topic in the interdisciplinary field of nuclear and astrophysics.

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.

For astrophysicists, neutron stars stand out as objects of irresistible fascination — perhaps, in part, because of how difficult they are to decipher. But calculations conducted on the Frontier ...
