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…
Approach of the NGC 1977 star cluster to the TOI-2796 host star
Hawi Yohanis Wakjira, D. A. Mosunova, E. S. Postnikova +2
We study of possible encounters in past epochs of the open star cluster NGC 1977 with host stars. For this purpose, the age of the cluster was determined based on our catalog data.…
A comprehensive analysis of NGC 2158 in Gaia era: photometric parameters, apex and orbit
Devesh P. Sariya, Ing-Guey Jiang, M. D. Sizova +7
We present an investigation of NGC 2158 using Gaia-DR2 data. We identified 800 most likely cluster members with membership probability higher than 90%. The mean proper motions of t…
Collinder 135 and UBC 7: A Physical Pair of Open Clusters
Dana Kovaleva, Marina Ishchenko, Ekaterina Postnikova +7
Given the closeness of the two open clusters Cr 135 and UBC 7 on the sky, we investigate the possibility of the two clusters to be physically related. We aim to recover the present…
Hyades star cluster and the New comets
M. D. Sizova, E. S. Postnikova, A. P. Demidov +2
We examined the influence of the Hyades star cluster on the possibility of the appearance of long-period comets in the Solar system. It is known that the Hyades cluster is extended…
The kinematical and space structures of IC 2391 open cluster and moving group with Gaia-DR2
E. S. Postnikova, W. H. Elsanhoury, Devesh P. Sariya +3
The kinematical parameters, spatial shape and structure of the open cluster IC 2391 and the associated stellar stream are studied here using Gaia-DR2 (GDR2) astrometry data. The ap…
