Radiatively driven, time dependent bipolar outflows

ABSTRACT We study the radiatively driven fluid jets around a non-rotating black hole. The radiation arising from inner compact corona and outer sub-Keplerian part of disc accelerates jets. obtain steady state, semi-analytical, outflow solutions. thermodynamics is described by variable adiabatic index equation state. develop total variation diminishing (TVD) routine to investigate time dependent behaviour bipolar outflow. inject with flow variables state solutions in TVD code allow settle into match numerical results solution. out accretion can provide wide range jet solutions, depending upon parameters like intensity disc, location etc. induce dependence field inducing oscillation disc. then makes dependent. show that non-steady oscillations generate internal shocks closer base. Depending on geometry, there might be transient multiple non-stationary jet, which are much interest physics.
