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 ...

Almost 25,000 light-years away, two dead stars, each more massive than our Sun, but only 20 kilometers in diameter, orbit one another in less than five hours. This unusual pair of extreme objects, ...

This illustration depicts a binary star system consisting of a dense neutron star and a normal Sun-like star (upper left). Using data from the European Space Agency's Gaia mission, astronomers found ...

Astronomers have discovered that radiation emitted by a rapidly spinning neutron star, or "pulsar," is dominated by the impact of its powerful particle winds — and not by the material it strips from a ...

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 ...

A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to ...

"This will help us understand how the jets are launched from all objects, even the supermassive black holes that reside at the centers of galaxies." When you purchase through links on our site, we may ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions. The ...
