Berkeley 32: A Metal-poor and Dynamically Evolved Open Cluster with Evidence of Radial Migration
Deniz Cennet Ãınar, 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…
Hot Degenerate Components in Blue Stragglers: A Multi-Wavelength SED Analysis of Nine Open Clusters with Swift/UVOT
Deniz Cennet Ãınar, D. Bisht, Selçuk Bilir +2
We present a homogeneous multi-wavelength analysis of 35 blue straggler star (BSS) candidates in nine open clusters, combining Swift/UVOT near-ultraviolet data with Gaia DR3 astrom…
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…
Revisiting the Orbital Dynamics of the Hot Jupiter WASP-12 b with New Transit Times
Shraddha Biswas, Ing-Guey Jiang, Li-Chin Yeh +10
In this study, we examine the transit timing deviations of the extensively studied hot Jupiter WASP-12 b using a comprehensive dataset of 391 transit light curves. The dataset incl…
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…
