We present the first results of eight globular clusters (GCs) from the AstroSat/UVIT Legacy Survey programme GlobULeS based on the observations carried out in two far-ultraviolet (FUV) filters (F148W and F169M). The ...
UVIT open cluster study. I. detection of a white dwarf companion to a blue straggler in M67: evidence of formation through mass transfer

Sindhu, N; Subramaniam, A; Jadhav, V. V; Chatterjee, Sourav; Geller, Aaron M; Knigge, Christian; Leigh, Nathan; Puzia, Thomas H; Shara, Michael; Simunovic, Mirko (IOP Publishing, 2019-09-01)

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 white dwarf (WD) companion to a BSS in ...
