Estimation of the Mass Outflow Rate From Compact Objects

Outflows are common in many astrophysical systems which contain black holes and neutron stars. Difference between stellar outflows and outflows from these systems is that the outflows in these systems have to form out of the inflowing material only. The inflowing material can form a hot and dense cloud surrounding the compact object either because of centrifugal barrier or a denser barrier due to pair plasma or pre-heating effects. This barrier behaves like a stellar surface as far as the mass loss is concerned. We estimate the outflow rate from such considerations. These estimated rates roughly match with the rates in real observations as well as those obtained from numerical experiments.

This is the first paper in the literature for computation of outflow rates from black hole inflow rates. It is heartening to see that several hyperactive workers are attracted to the same physics under the disguish of ADAF and ADIOS.

Gist of the present paper is in astro-ph/9803227, as a mild attempt to protect intelectual property. In the present version one paragraph in the introduction (justifying isothermal condition) is added. Submitted:24th July, 1997; Accepted: ......
