Estimating the Parameters of the Hybrid Palatini Gravity Model with the Schwarzschild Precession of S2, S38 and S55 Stars: Case of Bulk Mass Distribution

We estimate the parameters of Hybrid Palatini gravity model with Schwarzschild precession S-stars, specifically S2, S38 and S55 stars. also take into account case bulk mass distribution near Galactic Center. assume that orbital mentioned S-stars is same like in General Relativity (GR) all studied cases. In 2020 GRAVITY Collaboration detected S2 star around supermassive black hole (SMBH) at Center showed it close to GR prediction. The astronomical data analysis orbits these cases Based on this observational fact, we evaluated Gravity stars estimated range for which tree different values density extended matter. believe proposed method a useful tool evaluate gravitational potential
