Study reveals what causes 'outliers' track in black hole X-ray binaries
Black hole X-ray binaries (BHXB) comprise a stellar-mass black hole accreting gas from a companion star and emitting transient X-ray emission and compact radio jets.

Stars with the mass of the sun or larger are typically accompanied by one or more orbiting companion stars. The system forms when gravity contracts the gas and dust of an interstellar cloud until clumps develop that are dense ...

A supernova is the catastrophic explosion of a star. Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind. At least that's what models and observations suggested.

Astronomers from the Astronomical Observatory of Padova, Italy, and elsewhere have conducted observations of 25 stars as part of the COPAINS Pilot Survey. As a result, they detected four new brown dwarfs that received designations ...
NASA's Hubble Space Telescope has uncovered a witness at the scene of a star's explosive death: a companion star previously hidden in the glare of its partner's supernova. The discovery is a first for a particular type of ...
