A-type stars in the Canada–France Imaging Survey – II. Tracing the height of the disc at large distances with Blue Stragglers [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present the kinematics of Blue Straggler (BS) stars identified in the Canada-France-Imaging-Survey (CFIS), covering 4000 deg$^2$ on the sky in the $u$-band.

The radial distribution of blue stragglers in Galactic globular cluster NGC 6656 − clues to the dynamical status [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present dynamical status of the Galactic globular cluster NGC 6656 using spatial distribution of Blue Straggler Stars (BSSs). A combination of multi-wavelength high-resolution space and ground-based data are used to cover a large cluster region.

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).

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.

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.
