Berkeley 32: A Metal-poor and Dynamically Evolved Open Cluster with Evidence of Radial Migration

Deniz Cennet Çınar, D. Bisht, Ing-Guey Jiang +3

The study uses Gaia astrometry and Gaia-ESO spectroscopy to determine the age, metallicity, orbit, binary fraction, and dynamical state of the old, metal-poor open cluster Berkeley…

Blue Straggler Stars in Berkeley 18: A Multiwavelength Study of Their Physical Properties and Dynamical Evolution

D. Bisht, Ing-Guey Jiang, K. Belwal +7

Berkeley~18 is an old open cluster in the outer Galactic disk that hosts a population of blue straggler stars (BSSs). We present a comprehensive multiwavelength analysis of its BSS…

Evolution of the dusty nova QY Mus from eruption to quiescence

Mohit Singh Bisht, A. Raj, F. M. Walter +3

We present a comprehensive study of the spectrophotometric evolution of the classical nova QY Mus from eruption to quiescence. The light curve shows a notable dust dip, classifying…

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…

Time-Series Photometric Detection and Physical Characterization of Variable Stars in Four Intermediate- to Old-Age Galactic Open Clusters

K. Belwal, D. Bisht, Ing-Guey Jiang +4

We present a ground-based time-series photometric study of stellar variability in four intermediate- to old-age open clusters NGC 2192, NGC 2266, NGC 2509, and IC 1369 based on hig…

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…
