Abstract

Successive developments of the Newtonian approaches are presented to study the accretion processes around black holes. A number of ways the potentials are proposed simply to avoid the complexity of the general relativistic (GR) framework. We carefully review those pseudo-potentials. The constraints and limitations, success and failure, have also been addressed. We find the pseudo-Kerr potential in Mondal and Chakrabarti (Mon Not R Astron Soc 371:1418, 2006) is one of the best for GR predictions. Using this pseudo-Kerr potential, the particle dynamics and the accretion flow hydrodynamics have also been carried out. The results are compared with the GR and percentage of accuracy are also presented briefly.

We are thankful to Prof. SKC for making a sustained effort to have a simple minded potential for the Kerr geometry and I am proud to be a part of it. I acknowledge Mouli Chaudhuri while preparing this brief review.
