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…
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…
The Unexplored Dusty Nova LMCN 2009-05a in the Large Magellanic Cloud
Mohit Singh Bisht, A. Raj, F. M. Walter +4
We present a detailed spectrophotometric study of nova LMCN 2009-05a, located in the Large Magellanic Cloud (LMC). Photometric observations reveal a dust dip in the optical light c…
A Spectrophotometric analysis and dust properties of classical nova V5584 Sgr
Mohit Singh Bisht, A. Raj, F. M. Walter +4
In this work, optical observations of the nova V5584 Sgr are presented. These observations cover different phases including pre-maximum, early decline, and nebular. The spectra are…
The Dusty Aftermath of a Rapid Nova: V5579 Sgr
A. Raj, M. S. Bisht, F. M. Walter +10
V5579 Sgr was a fast nova discovered in 2008 April 18.784 UT. We present the optical spectroscopic observations of the nova observed from the Castanet Tolosan, SMARTS and CTIO obse…
