Interpretation of the light curves of quiescent X-ray novae in a model with a noncollisional interaction between the flow and disk. The XTE J1118+480 system

We have analyzed the orbital light curve of the X-ray nova XTE J1118+480 in a 'disk + hot line' model based on three-dimensional gas-dynamical computations of gas flows in interacting binary systems. As a result, we have been able to derive reliable parameters for the system: i = 80 -4 deg...

Description
Summary:We have analyzed the orbital light curve of the X-ray nova XTE J1118+480 in a 'disk + hot line' model based on three-dimensional gas-dynamical computations of gas flows in interacting binary systems. As a result, we have been able to derive reliable parameters for the system: i = 80 -4 degrees, MBH = 7.1 -0.1 M {circled dot}, M opt = 0.39 -0.07 M {circled dot}.
