Pseudo-Schwarzschild description of accretion-powered spherical outflow.

摘要

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, spherical shock around the central compact object. Then we self-consistently connect the accretion-wind solutions to calculate the mass outflow rate R-m in terms of a minimum number of flow parameters. We also study the dependence of this rate on various boundary conditions governing the flow. [References: 16]
