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 ...

Using ESA's XMM-Newton satellite, Italian astronomers have observed a Galactic X-ray binary system known as 4U 0728-25. Results of the new observations, presented in a research paper published March ...

For the study, the researchers analyzed 214 of the most massive stars in the Milky Way.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

Scientists have used NASA’s IXPE (Imaging X-ray Polarisation Explorer) to study a white dwarf star for the first time. By measuring the polarisation of X-rays, the mission allowed astronomers to ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...
