Probing Multiple Populations in Globular Clusters Using Stellar Streams

Just like the moon causes tides on the Earth, the Milky Way causes tides on star systems dropped into our galaxy. Globular clusters and dwarf galaxies that fall into the Milky Way's gravitational potential are slowly stripped of their stars until they fully disrupt into stellar streams. By spectroscopically observing stars in these streams, we can learn more about the environment in which these star clusters and dwarf galaxies formed. In this thesis, we explore for disrupting and fully disrupted stellar systems: ESO~280-SC06, the most metal-poor intact globular cluster in the Milky Way with a surprisingly high fraction of enriched stars; 300S, a globular cluster stream whose initial mass straddled the critical threshold for creating enriched stars; GD-1, a globular cluster stream that contains a star enriched by a binary companion, a rare find in globular clusters; and Leiptr, an ultra-faint dwarf galaxy stellar stream, the least massive disrupted dwarf galaxy identified to-date. Through the chemical analysis of these four systems, we learn more about the environment needed to form enriched stars in globular clusters, how the disruption of a globular cluster can impact the survival of binary stars, and the formation of dwarf galaxies on the smallest scales
