Formation Channels for Blue Straggler Stars [PDF]
, 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: Early Observations that Failed to Solve the Problem [PDF]
, 2014 In this chapter, I describe early ideas on blue stragglers, and various observations (some published, some not) that promised but failed to resolve the question of their origin.

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.

Blue Stragglers in Low-Luminosity Star Clusters [PDF]
The 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 ...

On the Variability of Blue Straggler Stars in the Globular Cluster M53 [PDF]
Journal of Astronomy and Space Sciences, 1998 We present the results of a search for photometric variable blue straggler stars (BSSs) in the globular cluster M53. Six of the 151 probable BSSs are identified as variable candidates based on the robust variable star detection technique of Welch ...

Characterization of Blue and Yellow Straggler Stars of Berkeley 39
The Astronomical JournalWe characterize blue straggler stars (BSSs) and yellow straggler stars (YSSs) of the open cluster (OC) Berkeley 39 using multiwavelength observations including the Swift/Ultraviolet and Optical Telescope (UVOT). Our analysis also makes use of ultraviolet

Blue Stragglers as Long-Lived Stars [PDF]
Symposium - 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 ...

On the Evidence of Disks around Blue Straggler Stars [PDF]
The Astrophysical Journal, 2005 Recent observations of blue stragglers by De Marco et al. (2004) have revealed continuum deficits on the blue side of the Balmer discontinuity, leading these authors to infer the presence of discs around the stars. This intriguing possibility may throw light on aspects of the mechanisms responsible for at least some of these objects; current theories ...

The Blue Straggler Stars of Galactic Clusters [PDF]
International Astronomical Union Colloquium, 1993 AbstractThe origin and evolution of blue straggler stars (BS) in clusters is still an unsolved problem for our understanding of stellar evolution. Several rivalling theories exist, of which that of Saio & Wheeler (1980) is the most interesting one since it assumes additional mixing of fuel in the interior of BS.

Blue Straggler Stars beyond the Milky Way. II. A Binary Origin for Blue Straggler Stars in Magellanic Cloud Clusters [PDF]
The Astrophysical Journal, 2018 Abstract We have analyzed populations of blue straggler stars (BSSs) in 24 Magellanic Cloud (MC) star clusters using multi-passband Hubble Space Telescope images. We compiled a homogeneous BSS database, containing both traditional and evolved BSSs.
