Star Clusters in the Ultraviolet

Annapurni Subramaniam, Samyaday Choudhury, Richard de Grijs +5

Ultraviolet (UV) observations provide a powerful window into the hot and evolved stellar populations that shape the structure, evolution and integrated light of star clusters. Beca…

Characterization of blue and yellow straggler stars of Berkeley 39 using Swift/UVOT

Komal Chand, Khushboo Rao, Kaushar Vaidya +1

We characterize blue straggler stars (BSS) and yellow straggler stars (YSS) of an open cluster (OC) Berkeley 39 using multi-wavelength observations including Swift/UVOT. Our analys…

Dynamical Evolution of Four Old Galactic Open Clusters traced by their constituent stars with \textit{Gaia} DR3

Shanmugha Balan, Khushboo K Rao, Kaushar Vaidya +2

We investigate the evolutionary stages of four open clusters, Berkeley 39, Collinder 261, NGC 6819, and NGC 7789, of ages ranging from 1.6 -- 6 Gyr. These clusters have previously…

UOCS-XII. A study of open cluster NGC 6940 using UVIT/AstroSat: cluster properties and exotic populations

Anju Panthi, Kaushar Vaidya

We study an open cluster NGC 6940 using \textit{AstroSat}/UVIT data and other archival data. This is an intermediate age cluster ( 1 Gyr), located at about 770 pc distance, h…

UOCS-XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat

Anju Panthi, Kaushar Vaidya, Nagaraj Vernekar +3

We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine learning-based algorithm, ML-MOC, on Ga…

Determination of dynamical ages of open clusters through the A parameter -- II

Khushboo K. Rao, Kaushar Vaidya, Manan Agarwal +2

Blue straggler stars (BSS), one of the most massive members of star clusters, have been used for over a decade to investigate mass segregation and estimate the dynamical ages of gl…
