The First Extensive Exploration of UV-bright Stars in the Globular Cluster NGC 2808
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu
In this study, we identified and characterized the hot and luminous UV-bright stars in the globular cluster NGC 2808. We combined data from the Ultra Violet Imaging Telescope (UVIT…
Study of UV bright stellar populations in the globular cluster NGC 1261 using AstroSat
Sharmila Rani, Gajendra Pandey, Annapurni Subramaniam +2
We present the UV photometry of the globular cluster NGC 1261 using images acquired with the Ultraviolet Imaging Telescope (UVIT) on-board ASTROSAT. We performed PSF photometry on…
Peculiarities in the horizontal branch stars of globular cluster NGC 1851: Discovery of a Blue straggler companion to an EHB star
Gaurav Singh, Snehalata Sahu, Annapurni Subramaniam +1
We present a study of Far Ultraviolet (FUV) bright horizontal branch (HB) stars to understand the peculiarities seen in the HB sequence of the Globular Cluster NGC 1851, using grou…
UVIT/ASTROSAT studies of Blue Straggler stars and post-mass transfer systems in star clusters: Detection of one more blue lurker in M67
Annapurni Subramaniam, Sindhu Pandey, Vikrant V. Jadhav +1
The blue straggler stars (BSSs) are main-sequence (MS) stars, which have evaded stellar evolution by acquiring mass while on the MS. The detection of extremely low mass (ELM) white…
Radial Distribution of Blue Stragglers in NGC 5466 using AstroSat
Snehalata Sahu, Annapurni Subramaniam
We present the results obtained from Near-UV observations of the cluster NGC 5466 taken with UVIT onboard AstroSat to study the radial distribution of Blue Straggler Stars (BSSs),…
Detection of a White Dwarf companion to a Blue Straggler Star in the outskirts of globular cluster NGC 5466 with the Ultraviolet Imaging Telescope (UVIT)
Snehalata Sahu, Annapurni Subramaniam, Mirko Simunovic +8
We report the discovery of a hot white dwarf (WD) companion to a blue straggler star (BSS) in the globular cluster (GC) NGC 5466, based on observations from the Ultra-Violet Imagin…
