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…

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…

A EDR3 search for tidal tails in disintegrating open clusters

Souradeep Bhattacharya, Khushboo K. Rao, Manan Agarwal +2

We carry out a search for tidal tails in a sample of open clusters with known relatively elongated morphology. We identify the member stars of these clusters from the precise astro…

UOCS-VIII. UV Study of the open cluster NGC 2506 using ASTROSAT

Anju Panthi, Kaushar Vaidya, Vikrant Jadhav +4

We study an intermediate-age open cluster NGC 2506 using the \textit{ASTROSAT}/UVIT data and other archival data. We identified 2175 cluster members using a machine learning-based…

Characterization of hot populations of Melotte 66 open cluster using Swift/UVOT

K. K. Rao, K. Vaidya, M. Agarwal +3

Ultraviolet (UV) wavelength observations have made a significant contribution to our understanding of hot stellar populations of star clusters. Multi-wavelength spectral energy dis…

Tidal tails in the disintegrating open cluster NGC 752

Souradeep Bhattacharya, Manan Agarwal, Khushboo K. Rao +1

We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5$^{…

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

Khushboo K. Rao, Kaushar Vaidya, Manan Agarwal +1

The sedimentation level of blue straggler stars (BSS) has been shown to be a great tool to investigate the dynamical states of globular clusters (GCs). The area enclosed between th…

Blue Straggler Populations of Seven Open Clusters with Gaia DR2

Kaushar Vaidya, Khushboo K. Rao, Manan Agarwal +1

Blue straggler stars (BSS) are well studied in globular clusters but their systematic study with secure membership determination is lacking in open clusters. We use Gaia DR2 data t…
