Search and analysis of blue straggler stars in open clusters

Astronomy and Astrophysics, 2006
Aims.This paper presents a new homogeneous catalogue of blue straggler stars (BSS) in Galactic open clusters. Methods: .Photometric data for 216 clusters were collected from the literature and 2782 BSS candidates were extracted from 76 of them. Results: .

Blue straggler stars

Blue straggler stars are unique main-sequence stars that appear more luminous, hotter, and therefore younger, than their coeval counterparts. In star clusters, these stars are located above the cluster turn-off in the Hertzsprung-Russell diagram or color-

Young blue straggler stars in the Galactic field [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
In this study, we present an analysis of a sample of field blue straggler (BS) stars that show high ultra violet emission in their spectral energy distributions (SEDs): indication of a hot white dwarf (WD) companion to BS.

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 the radial and rotational velocities for 110 blue straggler stars (BSSs) in ω Centauri, the globular cluster-like stellar system harboring the largest known BSS ...
