Blue Straggler Bimodality: A Brownian Motion Model [PDF]
The Astrophysical Journal, 2018 Abstract The shape of the radial distribution of blue straggler stars (BSS), when normalized to a reference population of horizontal branch (HB) stars, has been found to be a powerful indicator of the dynamical evolution reached by a globular cluster (GC).

WOCS 5379: Detailed Analysis of the Evolution of a Post-mass-transfer Blue Straggler [PDF]
, 2020 The blue straggler binary WOCS 5379 is a member of the old (6–7 Gyr) open cluster NGC 188. WOCS 5379 comprises a blue straggler star with a white dwarf companion in a 120 day eccentric orbit.

UVIT/AstroSat studies of blue straggler stars and post-mass transfer systems in star clusters: detection of one more blue lurker in M67 [PDF]
Journal of astrophysics and astronomy, 2020 The blue straggler stars (BSSs) are main-sequence (MS) stars, which have evaded stellar evolution by acquiring mass while on the MS. The detection of extremely low mass (ELM) white dwarf (WD) companions to two BSSs and one yellow straggler star (YSS ...

SPINNING LIKE A BLUE STRAGGLER: THE POPULATION OF FAST ROTATING BLUE STRAGGLER STARS IN ω CENTAURI [PDF]
The Astrophysical Journal, 2014 By using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured radial and rotational velocities for 110 Blue Straggler stars (BSSs) in Omega Centauri, the globular cluster-like stellar system harboring the largest known BSS population. According to their radial velocities, 109 BSSs are members of the system.

The Blue Straggler Population of the Open Clusters Trumpler 5, Trumpler 20, and NGC 2477 [PDF]
Astronomical Journal, 2020 We present a study based on Gaia DR2 of the population of blue straggler stars in the open clusters Trumpler 5, Trumpler 20, and NGC 2477. All candidates were selected according to their position in the color–magnitude diagram, their proper motion ...

Field population II blue stragglers
The Astrophysical Journal, 1981 Photometry and high-resolution spectra are presented and discussed of metal-poor stars hotter than the turn-off of globular clusters. Very few nonvariable candidates for blue stragglers can be identified One, HD 100363, is probably an old-disk short-period variable.

Blue Stragglers as Long-Lived Stars [PDF]
Symposium - International Astronomical Union, 1981 The existence of blue stragglers in old open clusters with apparent mass more than twice the mass of the turnoff argues against simple binary mass transfer as the mechanism of their origin. The excess of blue stragglers to the red of the termination of the core hydrogen burning main sequence suggests that blue stragglers are not evolving normally ...

On the Variability of Blue Straggler Stars in the Globular Cluster M53 [PDF]
Journal of Astronomy and Space Sciences, 1998 We present the results of a search for photometric variable blue straggler stars (BSSs) in the globular cluster M53. Six of the 151 probable BSSs are identified as variable candidates based on the robust variable star detection technique of Welch ...
