Mira variable stars in the galactic bulge and halo
Kateřina Neumannová
This work aimed to study Miras in the bulge and halo of our galaxy, including those in globular clusters. The AAVSO International Variable Star Index VSX catalogue was used to retr…
On the current status of tidal tails of Galactic open clusters
Tahereh Ramezani, Prapti Mondal, Katerina Neumannova +3
Tidal tails of open clusters provide direct observational evidence of cluster mass loss and dynamical interaction with the Galactic tidal field. The advent of astrometry has…
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…
Lightcurves of stars in the Chamaeleon I Association
K. Neumannová, L. Kueß, E. Paunzen +1
Star-forming regions are essential for studying very young stellar objects of various masses. They still contain a significant amount of dust and gas. We present a study of light c…
