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

Scientists first detected ripples in space known as gravitational waves from the merger of two black holes in September 2015.

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 ...

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 ...

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

An international team of researchers has announced a significant advancement in gravitational-wave astronomy, with the detection of 128 new cosmic collisions involving black holes and neutron stars.

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 ...
