Large offsets of double-neutron-star mergers: degeneracies and implications for host associations

Xiao-Tian Xu, Bin-Bin Zhang, Wenjie Wu +1

The projected offset of a Gamma-Ray Burst (GRB) from its host galaxy is an important diagnostic of its physical origin, where the host associations are usually evaluated through ch…

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…
