Dvojni sistemi zvezd vsebujejo dve zvezdi, ki krožita okrog skupnega masnega središča. V rentgenskih dvojnih sistemih je ena izmed zvezd zelo gost in majhen objekt, nevtronska zvezda. Nevtronska zvezda je ostanek jedra zvezde, ki je imela maso večjo od 8 sončevih mas. Prenos mase v rentgenskih dvojnih sistemih z veliko maso poteka zaradi močnih zvezdnih vetrov. V dvojnih sistemih z majhno maso pa se material prenaša preko Rochovega ovala.
A binary system is a system that contains two stars which orbit around the center of mass of the system. In an X-ray binary systems one of the two stars is a very small and dense object called a neutron star. A neutron star is a collapsed core of a star which had a mass of more than 8 solar masses. The mass transfer in a high-mass X-ray binary is driven by strong stellar winds and in a low-mass X-ray binary the mass is transferred via Roche lobe overflow.
