With the technical advancement of X-ray astronomy a new era has begun for the study of galactic outflows and in this context, Microquasars are a potential candidate. We simulate the winds driven by radiation from the Keplerian disk around microquasars. All components of radiative moments are incorporated in the governing hydrodynamic set of equations. We use a 2D, finite volume code based on TVD algorithm which is a second-order-accurate explicit scheme. We estimate the mass outflow rate depending on the Eddington parameter and compare our simulation result with the observations, as well as the fraction of mass being ejected to that being accreted onto the Black Hole is also calculated. |
