Direct N-body simulations of NGC 6397 and its tidal tails
Anthony D. Arnold, Holger Baumgardt
We have performed a series of direct N-body simulations that study the evolution of the Galactic globular cluster NGC 6397 under the combined influence of two-body relaxation, stel…
The influence of black holes on the binary population of the globular cluster Palomar 5
Long Wang, Mark Gieles, Holger Baumgardt +3
The discovery of stellar-mass black holes (BHs) in globular clusters (GCs) raises the possibility of long-term retention of BHs within GCs. These BHs influence various astrophysica…
Multimass modelling of Milky Way globular clusters -- II. present-day black hole populations
Nolan Dickson, Peter J. Smith, Vincent Hénault-Brunet +2
Populations of stellar-mass black holes (BHs) in globular clusters (GCs) influence their dynamical evolution and have important implications on one of the main formation channels f…
Testing QUMOND theory with Galactic globular clusters in a weak external field
A. Sollima, C. Nipoti, F. Calura +2
We developed self-consistent dynamical models of stellar systems in the framework of quasi-linear modified Newtonian dynamics (QUMOND). The models are constructed from the anisotro…
Multimass modelling of Milky Way globular clusters -- I. Implications on their stellar initial mass function above 1 M
Nolan Dickson, Vincent Hénault-Brunet, Holger Baumgardt +2
The distribution of stars and stellar remnants (white dwarfs, neutron stars, black holes) within globular clusters holds clues about their formation and long-term evolution, with i…
Multiple stellar populations at less evolved stages-III: a possible helium spread in NGC 2210
Chengyuan Li, Xin Ji, Long Wang +6
Helium variations are common features of globular clusters (GCs) with multiple stellar populations. All the formation scenarios predict that secondary population stars are enhanced…
