The contribution of Globular Clusters to the stellar halo using APOGEE and GAIA
Abstract
Over the last decade, much of the key questions in Galactic Archaeology have been asnwered by studying the Milky Way's globular cluster (GC) system. Following on this, it has been shown that a substantial fraction of the Milky Way's stellar halo field arises from GC dissolution. In this work, we make use of the latest data release fromn the APOGEE survey to study GC dissolution ratios in different spatial regions of the Galaxy. Our results will allow us to constrain many astrophysical questions, such as: the origin of N-Rich stars, the mass contribution from GCs to the stellar halo of the Galaxy, the origin of the Galactic GC system and the mass assembly of the Milky Way.
