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…
Detection of White Dwarf Companions to Blue Straggler Stars from UVIT Observations of M67
Sindhu N, Annapurni Subramaniam, Aaron M Geller +6
We investigate the old open cluster M67 using ultraviolet photometric data of Ultra-Violet Imaging Telescope in multi-filter far-UV bands. M67, well known for the presence of sever…
UVIT Open Cluster Study. I. Detection of a White Dwarf Companion to a Blue Straggler in M67: Evidence of Formation through Mass Transfer
N Sindhu, Annapurni Subramaniam, Vikrant V Jadhav +7
The old open cluster M67, populated with blue straggler stars (BSSs), is a well known test bed to study the BSS formation pathways. Here, we report the first direct detection of a…
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…
Constraints on blue straggler formation mechanisms in Galactic globular clusters from proper motion velocity distributions
N. W. C. Leigh, T. Panurach, M. Simunovic +10
For a sample of 38 Galactic globular clusters (GCs), we confront the observed distributions of blue straggler (BS) proper motions and masses (derived from isochrone fitting) from t…
