Cosmological insights into the early accretion of r-process-enhanced stars II. Dynamical identification of lost members of Reticulum II
P. Berczik, M. Ishchenko, O. Sobodar +1
Aims. We identify the possible dynamical connection between individual r-process-enhanced stars and the ultra-faint dwarf galaxy Reticulum II based on the current phase-space infor…
Evolution of the disky second generation of stars in globular clusters on cosmological timescale
Peter Berczik, Taras Panamarev, Maryna Ishchenko +1
Context. Many Milky Way globular clusters (GCs) host multiple stellar populations, challenging the traditional view of GCs as single-population systems. It has been suggested that…
Cluster membership analysis with supervised learning and -body simulations
A. Bissekenov, M. Kalambay, E. Abdikamalov +3
Membership analysis is an important tool for studying star clusters. There are various approaches to membership determination, including supervised and unsupervised machine learnin…
Dynamical evolution of Milky Way globular clusters on the cosmological timescale I. Mass loss and interaction with the nuclear star cluster
M. Ishchenko, P. Berczik, T. Panamarev +7
Context. Based on the Gaia DR3, we reconstructed the orbital evolution of the known Milky Way globular clusters and found that six objects, NGC 6681, NGC 6981, Palomar 6, NGC 6642,…
