UV photometry of spotted stars in the horizontal branch of the globular cluster NGC 2808 using AstroSat
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu
A recent study of hot (20,000 to 30,000 K) extreme horizontal branch (EHB) stars in globular clusters (GCs) has led to the discovery of their variability. It is suggested that this…
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…
UOCS. V. UV study of the old open cluster NGC 188 using AstroSat
Sharmila Rani, Annapurni Subramaniam, Sindhu Pandey +3
We present the UV photometry of the old open cluster NGC188 obtained using images acquired with Ultraviolet Imaging Telescope (UVIT) on board the ASTROSAT satellite, in two far-UV…
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…
