Cluster Membership Probabilities: A Review of Methods and Gaia Applications
Tahereh Ramezani, Johana Balciráková, Prapti Mondal +3
Reliable stellar-cluster membership is essential for deriving cluster ages, distances, reddenings, metallicities, mass functions, dynamical parameters, and Galactic-structure trace…
Tidal Tails of Galactic Open Clusters: A Review of Methods, Evidence, and Sources of Disagreement
Tahereh Ramezani, Prapti Mondal, Johana Balciráková +4
Tidal tails are a natural consequence of the dynamical evolution of open clusters in the Galactic tidal field, but their observational identification is intrinsically difficult bec…
The different methods to calculate cluster membership probabilities
Tahereh Ramezani, Prapti Mondal, Katerina Neumannova +3
Reliable membership determination is a fundamental step in the study of star clusters. With the advent of astrometry, a wide range of statistical and machine-learning techni…
Cluster characteristics of Galactic open clusters
K. Neumannová, J. Supíková, N. Faltová +4
Star clusters are perfectly suited for studying the formation, evolution, and dynamics of stars and their host galaxies. For this, we need to estimate total masses, radii and shape…
