Science at the edges: internal kinematics of globular clusters' external fields
Abstract
The outer regions of globular clusters (GCs) can enable us to answer many fundamental questions. The outskirts of GCs are still uncharted territories observationally. A very efficient way to explore them is through high- precision proper motions of low-mass stars over a large field of view. To do this, WFIRST represents the best observational tool.
