UOCS. XIV. Uncovering extremely low mass white dwarfs and blue lurkers in NGC 752

Vikrant V. Jadhav, Annapurni Subramaniam, Ram Sagar

Evolutionary pathways of binary systems are vastly different from single stellar evolution, and thus, there is a need to quantify their frequency and diversity. Open clusters are t…

UOCS XIII. Study of the FUV bright stars in the open cluster NGC 2420 using ASTROSAT

R. K. S. Yadav, Arvind K. Dattatrey, Geeta Rangwal +3

We present the study of four FUV stars in the field of open cluster NGC 2420 using the Ultra Violet Imaging Telescope (UVIT) mounted on AstroSat. The three stars 525, 527, and 560…

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…

UVIT/AstroSat Investigation of a low luminous Blue Straggler Star in NGC 362: Detection of extremely low mass white dwarf as companion

Arvind K. Dattatrey, R. K. S. Yadav, Annapurni Subramaniam +1

In the present study, we identified an extremely low-mass white dwarf as a companion to a low luminous blue straggler star within the Galactic globular cluster NGC 362. To conduct…

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…
