The evolution of globular cluster systems in galaxies., by Baumgardt, H.. Heidelberg Univ. (Germany). Naturwissenschaftlich-Mat
Mathematics
Scientific paper
This work considers the initial distribution and dynamical evolution of globular cluster systems in galaxies. Here, globular cluster systems start with power-law mass functions with slopes similar to what is observed for the young globular clusters seen in merging and interacting galaxies. The evolution of the globular clusters is followed in three different galaxies. In comparing the surviving distribution to the observed, the author shows that the model can reproduce several aspects of present day globular cluster systems. The Gaussian luminosity distribution observed for the globular clusters of the Milky Way and M87 is a product of the preferential destruction of low-mass clusters through internal relaxation. Furthermore, it is examined what portion of stars in the different galaxies were formed in globular clusters. Finally, comparing the evolution of globular clusters in different galaxies, the author investigates the reliability of the luminosity profile of a globular cluster system as a distance indicator.
