The dense central region of NGC 6397 contains three classes of stars whose origins are likely related to stellar interactions: blue stragglers, cataclysmic variables, and probable helium white dwarfs. We summarize results concerning CVs and HeWD candidates that have been identified in two imaging studies with Hubble Space Telescope, including one CV candidate that appears well outside the cluster core. We also present results concerning binaries containing two main sequence stars in the central…

Intermediate-mass black holes in binary-rich star clusters

There is both theoretical expectation and some observational clues that intermediate mass black holes reside in nuclei of globular clusters. In order to find an independent indicator for their

Fragmentation of Young Massive Clusters: A Hybrid Monte Carlo Simulation Study

To study the hierarchical fragmentation procedure in Young Massive Clusters, a stochastic model has been developed. Binary fragments along with individual stars are primarily studied in this work.

An analytical description of the evolution of binary orbital-parameter distributions in N-body computations of star clusters

A new method is presented to describe the evolution of the orbital-parameter distributions for an initially universal binary population in star clusters by means of the currently largest existing

A revolution in star cluster research: setting the scene

Improved understanding of the physics driving star cluster formation and evolution has led to the emergence of crucial new open questions that will most probably be tackled in a systematic way in the next decade.

3D-Spectroscopy of Dense Stellar Populations

The aim of this work is to prepare observations of globular clusters with the upcoming second-generation VLT instrument MUSE, which is an integral-field unit (IFU) with an outstanding combination of

White dwarfs have been known for slightly more than fifty years; with their planet-like diameters, and stellar-like masses their densities are enormously much higher than those of ‘normal’ stars.

The research and writing of a senior thesis is a capstone experience for a major in sociology. Since the thesis demands a great deal of independent thought and expression, it is a fitting culmination
