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-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…
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 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…
Disintegration of the Aged Open Cluster Berkeley 17
Souradeep Bhattacharya, Ishan Mishra, Kaushar Vaidya +1
We present the analysis of the morphological shape of Berkeley 17, the oldest known open cluster (~10 Gyr), using a probabilistic star counting of Pan-STARRS point sources, and con…
