Particle Motion and Parametric Constraints of Spherically Symmetric Space-time Using Observational Data

Abstract

This study focuses on parameters of spherically symmetric PRZ space-time and observa- tional test and implications on various astrophysical phenomena, Classical solar system tests arpund S2 star and Supermassive BH SgrA* at center of Milky way and studying QPO. The main aim to constrain the PRZ spacetime parameters. This is contribute to our understanding of GR and potential deviation in strong gravitational regimes.
