Pseudo-Schwarzschild description of accretion-powered spherical outflow

Abstract

Using two different pseudo-Schwarzschild potentials proposed by Artemova et. al, 1 we formulate and solve the equations governing spherically symmetric transonic inflow and outflow in presence of a relativistic hadronic pressure mediated steady, standing, spher- ical shock around the central compact object and then we self-consistently connect the accretion-wind solutions to calculate the mass outflow rate R ˙ m in terms of minimum number of flow parameters. Also we study the dependence of this rate on various bound- ary conditions governing the flow.
