SPINNING LIKE A BLUE STRAGGLER: THE POPULATION OF FAST ROTATING BLUE STRAGGLER STARS IN ω CENTAURI [PDF]
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.

Are All Blue Stragglers Ap Stars?
International Astronomical Union Colloquium, 1976SummaryA list of open clusters with blue stragglers studied for Ap characteristics is presented. In addition to previously published results new spectroscopic data are given of blue stragglers in the open cluster IC 4756 derived from ESO spectrograms taken in 1973. Preliminary conclusions concerning the status of Ap stars and blue stragglers are drawn.

Blue straggler stars in dwarf spheroidal galaxies - II. Sculptor and Fornax [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 The existence of blue straggler stars (BSSs) in dwarf spheroidal galaxies (dSphs) is still an open question. In fact, many BSS candidates have been observed in the Local Group dSphs, but it is unclear whether they are real BSSs or young stars. Shedding light on the nature of these BSS candidates is crucial, in order to understand the star formation ...

Abundance patterns in unevolved A stars and in blue stragglers
AIP Conference Proceedings, 1995On the basis of high‐resolution spectrometry and NLTE analysis we investigate abundance patterns of non‐nuclear origin in normal main‐sequence A stars and in their metal‐deficient counterparts, the Lambda Bootis stars. We try to identify and separate the effects of diffusion (gravitational settling, radiative levitation) and accretion (separation of ...

Rotational velocities of blue straggler stars in the globular cluster M 55
Astronomy and AstrophysicsBy using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured the radial and rotational velocities of 115 stars in the Galactic globular cluster M 55. After field decontamination based on the radial velocity values, the final sample of member stars is composed of 32 blue straggler stars (BSSs) and 76 reference stars ...

Report on the Workshop ''Ecology of Blue Straggler Stars''
2013The last workshop dedicated to blue straggler stars (BSS) took place 20 years ago and there have been a great number of subsequent developments since in both observations and theory. The wide range of BSS topics covered at the workshop are briefly summarised; the published proceedings will form the first book on the subject.
