Bayesian Characterization of Main Sequence Binaries in the Old Open Cluster NGC 188
Roger E. Cohen, Aaron M. Geller, Ted von Hippel
The binary fractions of open and globular clusters yield powerful constraints on their dynamical state and evolutionary history. We apply publicly available Bayesian analysis code…
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…
Constraining Mass Transfer Histories of Blue Straggler Stars with COS Spectroscopy of White Dwarf Companions
Natalie M. Gosnell, Emily M. Leiner, Robert D. Mathieu +4
Recent studies show that the majority of blue straggler stars (BSSs) in old open clusters are formed through mass transfer from an evolved star onto a main-sequence companion, resu…
Companion-driven evolution of massive stellar binaries
Sanaea C. Rose, Smadar Naoz, Aaron M. Geller
At least of massive OBA-type stars reside in binary or higher-order systems. The dynamical evolution of these systems can lend insight into the origins of extreme phenomena…
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…
