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…
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…
Hot Stellar Populations of Berkeley 39 using Swift/UVOT
Komal Chand, Khushboo Kunwar Rao, Kaushar Vaidya +1
Open clusters are excellent tools to probe the history of the Galactic disk and properties of star formation. In this work, we present a study of an old age open cluster Berkley 39…
Field blue straggler stars: Discovery of white dwarf companions to blue metal-poor stars using UVIT/AstroSat
Anju Panthi, Annapurni Subramaniam, Kaushar Vaidya +4
Blue metal-poor (BMP) stars are the main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters. They are believed to be eith…
Study of blue metal-poor stars using UVIT/AstroSat
Anju Panthi, Annapurni Subramaniam, Kaushar Vaidya +5
Blue metal-poor stars are main-sequence stars that are bluer and brighter than typical turn-off stars in metal-poor globular clusters. They are thought to have either evolved throu…
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…
UOCS VII. Blue Straggler Populations of Open Cluster NGC 7789 with UVIT/AstroSat
Kaushar Vaidya, Anju Panthi, Manan Agarwal +4
NGC 7789 is a 1.6 Gyr old, populous open cluster located at 2000 pc. We characterize the blue straggler stars (BSS) of this cluster using the Ultraviolet (UV) data from…
