Blue Stragglers in Low-Luminosity Star Clusters [PDF]
Astrophys.J.635:L73-L76,2005, 2005 We examine the blue straggler populations of 13 low-luminosity (M_V_t >~ -6) globular clusters and 2 old open clusters. These clusters test blue straggler formation in environments intermediate between higher luminosity (and usually higher density) clusters and the Galactic field. The anti-correlation between the relative frequency of blue stragglers

Fast-rotating Blue Straggler Stars in the Globular Cluster NGC 3201
The Astrophysical Journal, 2023 We used high-resolution spectra acquired with the Magellan Telescope to measure radial and rotational velocities of approximately 200 stars in the Galactic globular cluster NGC 3201.

Search and analysis of blue straggler stars in open clusters [PDF]
Astronomy & 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: We found that the anticorrelation of BSS frequency vs. total magnitude identified in similar studies

The Astronomical JournalWe identified blue straggler stars (BSSs) in 53 open clusters utilizing data from Gaia DR3. Most of these clusters are situated in the outer regions of the Galactic disk, encompassing structures such as the warp and the Outer arm.

On blue straggler formation by direct collisions of main sequence stars [PDF]
The Astrophysical Journal, 1995 We report the results of new SPH calculations of parabolic collisions between main-sequence (MS) stars. The stars are assumed to be close to the MS turn-off point in a globular cluster and are therefore modeled as $n=3$, $ =5/3$ polytropes. We find that the high degree of central mass concentration in these stars has a profound effect on the ...

WEIGHING STARS: THE IDENTIFICATION OF AN EVOLVED BLUE STRAGGLER STAR IN THE GLOBULAR CLUSTER 47 TUCANAE* [PDF]
The Astrophysical Journal, 2016 ABSTRACT Globular clusters are known to host peculiar objects named blue straggler stars (BSSs), significantly heavier than the normal stellar population. While these stars can be easily identified during their core hydrogen-burning phase, they are photometrically indistinguishable from their low-mass sisters in advanced stages of the ...
