The Blue Stragglers of the Old Open Cluster NGC 188 [PDF]
, 2014 The old (7 Gyr) open cluster NGC 188 has yielded a wealth of astrophysical insight into its rich blue straggler population. Specifically, the NGC 188 blue stragglers are characterized by: A binary frequency of 80% for orbital periods less than $10^4 ...

Blue Stragglers from Primordial Binary Evolution [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractBinaries exist in all clusters and much evidence suggests that close-binary evolution makes an important contribution to the blue straggler population, at least in some clusters as well as in the field. Here we present different channels to blue stragglers from primordial binary evolution and examine their contributions to the integrated ...

Field Blue Stragglers and Related Mass Transfer Issues [PDF]
, 2014 I view field blue stragglers (FBS) through the prism of an aging observer. This chapter contains my impressions and perspectives about the current state of knowledge about FBSSs, drawn from an extensive literature that I searched with the aid of the NASA

Exotic populations in globular clusters: blue stragglers as tracers of the internal dynamical evolution of stellar systems [PDF]
Proceedings of the International Astronomical Union, 2014 In this paper I present an overview of the main observational properties of a special class of exotic objects (the so-called Blue Straggler Stars, BSSs) in Galactic Globular Clusters (GCs).

Astronomy & AstrophysicsContext. We present an observational and theoretical study of the complex stellar system S1082 in the open cluster M67. This system consists of at least four stars: a blue straggler in a 1.07-day eclipsing binary with a main sequence star (binary A) and ...

Color Gradients Within Globular Clusters: Restricted Numerical Simulation [PDF]
Journal of Astronomy and Space Sciences, 1997 The results of a restricted numerical simulation for the color gradients within globular clusters have been presented. The standard luminosity function of M3 and Salpeter's initial mass functions were used to generate model clusters as a fundamental ...

DETECTION OF WHITE DWARF COMPANIONS TO BLUE STRAGGLERS IN THE OPEN CLUSTER NGC 188: DIRECT EVIDENCE FOR RECENT MASS TRANSFER [PDF]
, 2014 Several possible formation pathways for blue straggler stars have been developed recently, but no one pathway has yet been observationally confirmed for a specific blue straggler.

Fast-rotating blue straggler stars in the globular cluster NGC 1851
Astronomy & AstrophysicsWe studied the rotational velocities of a sample of blue straggler stars (BSSs) and reference stars belonging to the Galactic globular cluster NGC 1851 using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT. After field decontamination

Chemical composition of a palomar 12 blue straggler
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT With the equivalent area of a 16-m telescope, ESPRESSO in 4UT mode allows to inaugurate high resolution spectroscopy for solar-type stars belonging to extragalactic globular clusters. We determine the chemical composition of an extragalactic blue straggler (BS).
