Description
Globular Clusters (GCs) in the Milky Way and dwarf spheroidal galaxies (dSphs) around the Milky Way are nearby laboratories for the study of stellar populations with different masses, ages, and densities. In general, the stellar population in GCs has a significantly higher number density than that of the dSphs. While in dSphs the main population of binary systems are expected to be of primordial nature, formed at the first stages of galaxy evolution, binary systems in dense GCs might have also formed later in their evolution in dynamical interactions. Observations can help us to understand the effect of dynamical interactions on the evolution of binary systems. We present our recent results of X-ray population studies of dSphs (Draco, Sculptor, Willman 1, Leo I, and the centre of Sagittarius dSph) observed with XMM-Newton and Chandra. We also present the first results of the eROSITA observations of the 47 Tucanae Globular Cluster.
