Formation Channels for Blue Straggler Stars [PDF]

open access: yes, 2014
In this chapter we consider two formation channels for blue straggler stars: 1) the merger of two single stars via a collision, and 2) those produced via mass transfer within a binary.

Blue Straggler Stars in Galactic Open Clusters and the effect of field star contamination [PDF]

open access: yesAstronomy & Astrophysics, 2008
We investigate the distribution of Blue Straggler stars in the field of three open star clusters. The main purpose is to highlight the crucial role played by general Galactic disk fore-/back-ground field stars, which are often located in the same region ...

Fast-rotating Blue Straggler Stars in the Globular Cluster NGC 3201

open access: yesThe 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.

Blue Stragglers in Low-Luminosity Star Clusters [PDF]

open access: yesThe Astrophysical Journal, 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 ...

Blue Stragglers as Long-Lived Stars [PDF]

open access: bronzeSymposium - International Astronomical Union, 1981
The existence of blue stragglers in old open clusters with apparent mass more than twice the mass of the turnoff argues against simple binary mass transfer as the mechanism of their origin. The excess of blue stragglers to the red of the termination of the core hydrogen burning main sequence suggests that blue stragglers are not evolving normally ...

Observations of blue straggler stars in globular clusters [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2006
AbstractBlue stragglers stars (BSS) define a sparsely populated sequence extending to higher luminosity than the turnoff point of normal main sequence stars in the color magnitude diagrams of stellar aggregates, thus mimicking a rejuvenated (more massive) stellar population. The nature of these stars has been a puzzle for many years and their formation

The Multiple Origin of Blue Straggler Stars: Theory vs. Observations [PDF]

open access: yes, 2014
In this chapter we review the various suggested channels for the formation and evolution of blue straggler stars (BSSs) in different environments and their observational predictions.
