Non-inertial Force Effects on Milky Way Globular Cluster Dynamics

ORAL

Abstract

Globular clusters orbit the Milky Way and depending on the initial conditions, can influence whether or not stars within the cluster escape. Factors such as the energy and initial position can not only influence whether a star escapes, but also at what time and angle it passes the tidal radius. The presence of escapers in globular clusters and the orbital parameters can affect N-body simulations because of the mass loss within the cluster, which is an important component of orbital dynamics research. There currently exist models depicting the trajectories of stars in globular clusters with varying energies to show how the escape times and angles change. Being able to develop and expand upon existing models for the motion of stars can improve an understanding of globular cluster evolution and tidal streams. The goal of this project is to expand on previous work done by extending this model to elliptical orbits in order to determine the impact that non-inertial forces have on the escape time and angle of stars in globular clusters using a Plummer potential profile.
