Retrograde Precession of Relativistic Orbits and the Quest for Charged Black Holes

Parth Bambhaniya, Meet J. Vyas, Pankaj S. Joshi +1

The S-stars around the center of the milky way galaxy provide us with detailed information about the nature of the supermassive compact object Sagittarius A* (Sgr A*). In this work…
