Statistical study for binary star evolution in dense embedded clusters
Wenjie Wu, Pavel Kroupa, Vikrant V. Jadhav
Context: The dynamical evolution of binary populations in embedded star clusters shapes the statistical properties of binaries observed in the Galactic field. Accurately modelling…
Tidal Tails of Nearby Open Clusters. II. A Review of Simulated Properties and the Reliability of Observational Catalogues
Vikrant V. Jadhav, Dhanraj Risbud, Pavel Kroupa +1
Context: Recent studies using Gaia data have reported tidal tail detections for tens to hundreds of open clusters. However, a comprehensive assessment of the reliability & complete…
The evolution of the mass--radius relation of expanding very young star clusters
Jian-Wen Zhou, Pavel Kroupa, Wenjie Wu
The initial mass--radius relation of embedded star clusters is an essentially important boundary condition for understanding the evolution of embedded clusters in which stars form…
Open star clusters and their asymmetrical tidal tails
Pavel Kroupa, Jan Pflamm-Altenburg, Sergij Mazurenko +4
Stars that evaporate from their star cluster by the energy equipartition process end up either in a leading or a trailing tidal tail. In Newtonian gravitation and for open star clu…
Mass segregation and velocity dispersion as evidence for a dark star cluster
Wenjie Wu, Pavel Kroupa, Jan Pflamm-Altenburg
A dark star cluster (DSC) is a system in which the cluster potential is dominated by stellar remnants, such as black holes and neutron stars having larger masses than the long-live…
The spin, expansion and contraction of open star clusters
Vikrant V. Jadhav, Pavel Kroupa, Wenjie Wu +2
Empirical constraints on the internal dynamics of open clusters are important for understanding their evolution and evaporation. High precision astrometry from Gaia DR3 are thus us…
