X-ray binary stars are basically X-ray sources that are members of a binary system.
They are a class of binary stars that produce a large quantity of X-rays. The X-rays are produced by matter falling from one of the members, called the donor, which is usually a relatively normal star, to the other component, called the accretor, which is generally a collapsed star like a white dwarf, neutron star, or black hole.Â?
The fallen matter releases its gravitational potential energy as X-rays.
Note: A binary star system is a system containing two stars that orbit around their common center of mass.

X-ray binary stars are binary star systems in which one of the stars is a compact object, such as a neutron star or black hole, that accretes mass from its companion star. This accretion process can generate intense X-ray emission, making X-ray binaries detectable by X-ray telescopes. These systems provide valuable information about the behavior of compact objects and the physics of accretion.
Two stars orbiting each other are "binary stars" ...a group of stars near each other, may be formally or informally known as a "cluster".
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
The masses of the two stars.
Stars found in pairs are called binary stars. Binary stars orbit around a common center of mass due to gravitational attraction between them.
Binary stars can appear in a variety of colors depending on the characteristics of the individual stars. The colors can range from blue or white for hotter stars to red for cooler stars. The combination of these colors can create unique visual effects when viewed together in the sky.
