Binary disruption during the early phase of open clusters
Zepeng Zheng, Long Wang, Holger Baumgardt
The binary fraction in young open clusters exceeds that of field stars, making the study of binary dynamical evolution in clusters essential for understanding the origins and evolu…
On the connection between nitrogen-enhanced field stars and the Galactic globular clusters
Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6
As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…
Stellar mass segregation as separating classifier between globular clusters and ultra-faint dwarf galaxies
Holger Baumgardt, Johannes Faller, Nicholas Meinhold +2
We have determined the amount of stellar mass segregation in over 50 globular clusters and ultra-faint dwarf galaxy candidates based on deep HST and ground-based photometry. We fin…
Mass segregation and fractal substructure in young massive clusters: (I) the McLuster code and method calibration
A. H. W. Kuepper, Th. Maschberger, P. Kroupa +1
By analysing models of the young massive cluster R136 in 30 Doradus, set-up using the herewith introduced and publicly made available code McLuster, we investigate and compare diff…
Evolution of two stellar populations in globular clusters II. Effects of primordial gas expulsion
T. Decressin, H. Baumgardt, C. Charbonnel +1
We investigate the early evolution of two distinct populations of low-mass stars in globular clusters under the influence of primordial gas expulsion driven by supernovae to study…
The velocity dispersion and mass-to-light ratio of the remote halo globular cluster NGC 2419
H. Baumgardt, P. Cote, M. Hilker +4
Precise radial velocity measurements from HIRES on the Keck I telescope are presented for 40 stars in the outer halo globular cluster NGC 2419. These data are used to probe the clu…
