GlobULeS-V. UVIT/AstroSat studies of stellar populations in NGC 362: Detection of Blue Lurkers in a Globular Cluster
Arvind K. Dattatrey, R. K. S. Yadav, Gourav Kumawat +4
We report the discovery of four blue lurkers with low and extremely low-mass white dwarf (ELM WDs) companions in the Galactic globular cluster NGC 362 using AstroSat Ultra Violet I…
GlobULeS-IV. UVIT/AstroSat detection of extremely low mass white dwarf companions to blue straggler stars in NGC 362
Arvind K. Dattatrey, R. K. S. Yadav, Sharmila Rani +4
We report the discovery of extremely low-mass white dwarfs (ELM WDs) as a companion of blue straggler stars (BSSs) in the Galactic globular cluster NGC 362 using images from AstroS…
Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21
We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…
Globular Clusters UVIT Legacy Survey (GlobULeS) I. FUV-optical Color-Magnitude Diagrams for Eight Globular Clusters
Snehalata Sahu, Annapurni Subramaniam, Gaurav Singh +22
We present the first results of eight Globular Clusters (GCs) from the AstroSat/UVIT Legacy Survey program GlobULeS based on the observations carried out in two FUV filters (F148W…
Study of dynamical status of the globular cluster NGC 1851 using Ultraviolet Imaging Telescope
Gaurav Singh, R. K. S. Yadav, Snehalata Sahu +1
We present the study of dynamical status of the globular cluster NGC 1851. A combination of multiwavelength space and ground-based data sets are used for the present analysis. In o…
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…
The radial distribution of Blue stragglers in Galactic Globular Cluster NGC 6656 Clues on the dynamical status
Gaurav Singh, R. K. S. Yadav
We present dynamical status of the Galactic globular cluster NGC 6656 using spatial distribution of Blue Straggler Stars (BSSs). A combination of multi-wavelength high-resolution s…
