X-Ray binary

X-Ray binary 
X-Ray binary are a type of Binary star system that has a star, called a donor (usually a main sequence star) and an accretor, the accretor is either a neutron star or black hole. The donor gives matter to the accretor. The systems are luminous in X-Rays which are formed from the matter falling from the donor. 

 Classification 
X-Ray binaries are subdivided into several subclasses. They include:

Low-mass X-ray binary (LMXBs)

Soft X-ray transients (SXTs)

Symbiotic X-ray binary

Super soft X-ray sources (SSXs)

Accreting millisecond X-ray pulsars (AMXPs)

Intermediate-mass X-ray binary (IMXBs)

Be/X-ray binary (BeXRBs)

Supergiant X-ray binary (SGXBs)

Supergiant fast X-ray transients (SFXTs)
