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…

Characterizing Blue Straggler Star Populations in Globular Clusters using HST Photometric Survey Data

Mirko Simunovic, Thomas H. Puzia

We present early results from a detailed analysis of the BSS population in Galactic GCs based on HST data.Using proper motion cleaning of the color-magnitude diagrams we construct…
