Dynamical evolution of the open clusters with different star formation efficiencies and orbital parameters
M. Ishchenko, V. Masliukh, M. Hradov +3
Open star clusters are dynamic systems whose evolution is critically influenced by initial conditions such as star formation efficiency and orbital parameters. Understanding their…
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,…
Star-by-star dynamical evolution of the physical pair of the Collinder 135 and UBC 7 open clusters
Maryna Ishchenko, Dana A. Kovaleva, Peter Berczik +8
In a previous paper using Gaia DR2 data, we demonstrated that the two closely situated open clusters Collinder 135 and UBC 7 might have formed together about 50 Myr ago. In this wo…
Milky Way globular clusters on cosmological timescales. III. Interaction rates
Maryna Ishchenko, Margaryta Sobolenko, Peter Berczik +4
Aims. We carry out the self-consistent dynamic evolution of the orbital structure of Milky Way globular clusters. This allows us to estimate possible and probable close passages an…
Milky Way globular clusters on cosmological timescales. I. Evolution of the orbital parameters in time-varying potentials
M. Ishchenko, M. Sobolenko, P. Berczik +4
Context. Recent observational data show that the Milky Way (MW) galaxy contains about 170 globular clusters (GCs). A fraction of them is likely formed in dwarf galaxies accreted on…
