Detection of White Dwarf companions to Blue Straggler Stars from UVIT observations of M67

Sindhu, N; Subramaniam, A; Geller, A. M; Jadhav, Vikrant; Knigge, Christian; Simunovic, Mirko; Leigh, Nathan; Shara, Michael; Puzia, T. H (Cambridge University Press, 2019-05)

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 several blue straggler stars (BSS), has been ...
UVIT open cluster study. I. detection of a white dwarf companion to a blue straggler in M67: evidence of formation through mass transfer
