Stable Circular orbit in the Equatorial plane of Black hole - Softcover

Inhaltsangabe

A detailed study of the properties of time –like and Null geodesics, specially of stable circular orbits, in the charge free Kerr metric have been presented by Bardeen, has been made. In the case of Bardeen, the three direct orbits radius of marginally stable circular, radius of marginally bound orbit and radius for circular photon orbit, all seems to concide with the event horizon in extreme Kerr black hole. He has also obtained the three orbits rms= 6m, rmb=4m and rph=3m for schwarzs child metric. But in his case there are no circular orbits corresponding to rms=6m rmb=4m, and rph=3m, conciding with event horizon. I have to put the fact that in addition to the stable circular orbits obtained by Bardeen, there exists a circular orbit out side the ergo sphere of the Kerr black hole where all these direct orbits (marginally stable, the marginally bound and the circular photon orbits) coincide. I have tried my best to show first of in the world the storage of energy due to celestial objects due to gravitational collapse is possible in the Skylab.
