In a significant breakthrough, astronomers have recently discovered a “ghost star” nestled within the remnants of a supernova ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

Astronomers have doubled the number of black hole and neutron star mergers detected via gravitational waves in a "stellar ...

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

Scientists led by Tel Aviv University’s Tomer Shenar, with Hugues Sana of KU Leuven and Julia Bodensteiner of the University ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

"It's pretty incredible to think that some of the heavy elements all around us, like the precious metals in our phones and computers, are produced in these crazy extreme environments." Scientists have ...

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new ...
