• # Abstract

We study the dynamics of a test particle around a central mass taking into account general relativistic effects within the formalism of Lagrangian mechanics, and investigate a real astrophysical object to probe the model. We consider a generalized potential for the Lagrangian of the particle, compute thecorresponding equations of motion, and present a numerical scheme to integrate them. Within this approach, we run simulations to fit the orbital parameters of the star S2 around the SMBH Sgr A$^*$, using a Markov Chain Monte Carlo method. We estimate the radius and speed of the star at periapsis, its apsidal precessionand the black hole mass. Our results are consistent with results available in previous literature.

Posted on January 27, 2016

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
