Multiwavelength Study of Blue Straggler Stars in Tombaugh 2: Evidence for Binary Mass Transfer and Constraints on Cluster Dynamical State
D. Bisht, Ing-Guey Jiang, K. Belwal +7
We present a focused multiwavelength study of blue straggler stars (BSSs) in the intermediate-age open cluster Tombaugh 2, located in the outer Galactic disk, to constrain the domi…
Dynamical and Photometric Analysis of NGC 146 and King 14: Evidence for a Co-Moving, Unbound Cluster Pair
D. Bisht, Ing-Guey Jiang, W. H. Elsanhoury +9
To understand the nature of the NGC 146-King 14 cluster pair, we conducted a detailed photometric, astrometric, and dynamical study using multiwavelength data from Gaia DR3, Pan-ST…
Unveiling Dynamics and Variability in Open Clusters: Insights from a Comprehensive Analysis of Six Galactic Clusters
Kuldeep Belwal, D. Bisht, Ing-Guey Jiang +6
We present a kinematic and dynamical analysis of six Galactic open clusters NGC~2204, NGC~2660, NGC~2262, Czernik~32, Pismis~18, and NGC~2437, using \textit{Gaia}~DR3. We used Baye…
Detection of young massive white dwarfs in core-collapsed globular cluster NGC 362
R. K. S. Yadav, Arvind K. Dattatrey, Annapurni Subramaniam +2
Core-collapsed globular clusters are ideal targets to explore the presence of stellar collision products. Here, we have studied seventeen FUV bright white dwarf members in the glob…
Spectroscopic Study of Blue Straggler Stars in the Globular Cluster NGC 3201
Gourav Kumawat, Arvind K. Dattatrey, R. K. S Yadav
We conducted a spectroscopic study of 39 blue straggler stars in the globular cluster NGC 3201. The spectra of these stars were collected from the literature. We determined the rad…
Investigating open cluster King 6: Detection of three new variables
Vaibhav Kumar Pandey, Arvind K Dattatrey, Apara Tripathi +2
This study presents photometric analysis of the intermediate-age open cluster King 6, utilizing photometric data in UBV(RI) passband and data from the 2MASS mission. The Gaia D…
