Tracing Radial Migration in the Outer Disk: A Comprehensive Analysis of the Old Open Cluster Berkeley 36
Deniz Cennet Çınar, D. Bisht, Ing-Guey Jiang +2
We present a chemo-kinematical, structural, and photometric analysis of the old open cluster Berkeley 36 using Gaia DR3 astrometry and photometry together with high-resolution spec…
Berkeley 32: A Metal-poor and Dynamically Evolved Open Cluster with Evidence of Radial Migration
Deniz Cennet Çınar, D. Bisht, Ing-Guey Jiang +3
We present a comprehensive chemo-dynamical analysis of the old, metal-poor open cluster Berkeley 32 based on Gaia DR3 astrometry and Gaia-ESO Survey DR5.1 spectroscopy. Cluster mem…
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…
