The properties of Galactic globular cluster sub - systems
In this paper we compare the properties of three sub-systems of Galactic globular clusters, which are defined according to metallicity and horizontal branch morphology. We specifically focus on cluster luminosities, structures, surface brightnesses and ellipticities. It is shown that the so-called “young” halo (YH) clusters, which are thought to have formed in external satellite galaxies, exhib...
متن کاملDestruction of the Galactic Globular Cluster System
We investigate the dynamical evolution of the Galactic Globular Cluster System in considerably greater detail than has been done hitherto, finding that destruction rates are significantly larger than given by previous estimates. The general scheme (but not the detailed implementation) follows Aguilar, Hut, & Ostriker (1988; AHO). For the evolution of individual clusters we use a Fokker-Planck c...
متن کاملEvolution of the Galactic Globular Cluster System
We study the dynamical evolution of disk and halo globular clusters in the Milky Way using a series of Fokker-Planck calculations combined with parametric statistical models. Our sample of 113 clusters with velocity data is predicted to descend from an initial population of 250 clusters, implying more than a factor of two decrease in population size due to evolution. Approximately 200 of these ...
متن کاملComparing the properties of local globular cluster systems: implications for the formation of the Galactic halo
We investigate the hypothesis that some fraction of the globular clusters presently observed in the Galactic halo formed in external dwarf galaxies. This is done by means of a detailed comparison between the “old halo”, “young halo,” and “bulge/disk” sub-systems defined by Zinn (1993a) and the globular clusters in the LMC, SMC, and Fornax and Sagittarius dwarf spheroidal galaxies. We first use ...
متن کاملThe Effect of the Galactic Spheroid on Globular Cluster Evolution
We study the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution, exploring the physical consequences of external effects and examining evolutionary trends in the Milky Way population. Our analysis demonstrates that heating on circular and low-eccentricity orbits can dominate cluster evolution. The results also predict rapid evolution on eccentric orbi...
