TLDR
Galactic globular clusters represent unique laboratories for learning about two-body relaxation, mass segregation from equipartition of energy, stellar collisions, stellar mergers, and core collapse as mentioned in this paper.Abstract:
Galactic globular clusters, which are ancient building blocks of our Galaxy, represent a very interesting family of stellar systems in which some fundamental dynamical processes have taken place on time scales shorter than the age of the universe. In contrast with galaxies, these clusters represent unique laboratories for learning about two-body relaxation, mass segregation from equipartition of energy, stellar collisions, stellar mergers, and core collapse. In the present review, we summarize the tremendous developments, as much theoretical as observational, that have taken place during the last two decades, and which have led to a quantum jump in our understanding of these beautiful dynamical systems.read more

Abundance Variations within Globular Clusters
TL;DR: Abundance variations within globular clusters (GCs) and of GC stars with respect to field stars are important diagnostics of a variety of physical phenomena, related to the evolution of individual stars, mass transfer in binary systems, and chemical evolution in high density environments as mentioned in this paper.

TL;DR: In this article, it was shown that metal-poor GCs formed in low-mass dark matter halos in the early universe and that their properties reflect biased galaxy assembly, while metal-rich GCs were born in the subsequent dissipational buildup of their parent galaxies.

TL;DR: In this paper, the second data release of the Gaia mission and its power for constraining many different aspects of the dynamics of the satellites of the Milky Way is demonstrated. But the accuracy of the errors, statistical and systematic, are relatively well understood.

TL;DR: In this article, the authors present conclusive observational evidence of a link between the number of close binaries observed in X-rays in a globular cluster and the stellar encounter rate of the cluster, and make an estimate of the total number of LMXBs in globular clusters in our Galaxy.
