Orbital Dynamics Using Pseudo-Newtonian Potential

摘要

209.1 Introduction The Pseudo-Newtonian Potentials (PNPs), which are constructed/proposed to replicate few general relativistics features approximately in Newtonian framework, are often used to study inner relativistic dynamics of the accretion flow around spacetime geometries describing black holes. For a general class of static spherically symmetric space time metrics {formula}, where f(r) is the generic metric function, p is an arbitrary constant parameter, the PNP can be written as [1]{formula}
