Using various space observatories, astronomers have performed X-ray polarimetric and spectral observations of a bright low-mass X-ray binary known as Serpens X-1. Results of the observational campaign ...

ESA’s Integral gamma-ray observatory has discovered a new, highly populated class of X-ray fast ‘transient’ binary stars, undetected in previous observations. With this discovery, Integral confirms ...

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 ...

Imagine two stars with winds so powerful that they eject an Earth’s worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce ...

X‐ray binaries serve as natural laboratories for investigating the extreme physics of accretion and relativistic phenomena. These systems, comprising a compact object – typically a black hole or ...
