Dynamics of the Intermediate-Age Elliptical LMC Cluster NGC 1978
Philippe Fischer, Douglas L. Welch, Mario Mateo
Abstract
In this paper we investigate the internal dynamics of the LMC cluster NGC 1978 through the use of Photometric (CCD images) and kinematic (stellar radial velocities) data. We apply a variety of dynamical models to this data, including multi-mass King-Michie models and rotating and non-rotating oblate spheroid models. We discuss the cluster mass-to-light ratio and place constraints on the cluster mass function.
