Vertical structure of accretion discs in LMXB A. Tavleev, K. Malanchev, G. Lipunova

Abstract

      A low-mass X-ray binary (LMXB) is a binary system where one of the components is either a neutron star or a black hole. The other component (donor, usually a main sequence star) fills its Roche lobe and therefore looses mass to the compact object. We calculate the vertical structure of an accretion disc formed around the compact object. We develop a flexible numerical code, which allows us to change the equation of state, opacity law, and chemical composition. Our calculations can improve the accuracy of the modeling of LMXB outbursts.
