Allan Sandage: Blue Stragglers
2021One of the more recent stellar discoveries was made by noticing something out of place in globular cluster Messier 3 (M3) (Fig. 19.1).

Spectroscopic Study of Blue Straggler Stars in the Globular Cluster NGC 3201
Revista mexicana de astronomía y astrofísicaWe conducted a spectroscopic study of 39 blue straggler stars in the globular cluster NGC 3201. The spectra of these stars have been previously reported.

Detection of a white dwarf orbiting a carbon-oxygen-depleted blue straggler in 47 Tucanae
Astronomy & AstrophysicsWe employed deep far-UV observations secured with the Solar Blind Channel of the Advanced Camera for Surveys onboard the Hubble Space Telescope to search for hot companions to five blue straggler stars (BSSs) showing significant surface depletion of ...

Rendiconti Lincei SCIENZE FISICHE E NATURALI, 2020
We discuss the observational properties of a special class of objects (the so-called “Blue Straggler Stars”, BSSs) in the framework of using this stellar population as probe of the dynamical processes occurring in high-density stellar systems.

Blue Straggler Stars of NGC 7789 and NGC 2506 Using AstroSat/UVIT
Bulletin de la Société royale des sciences de LiègeBlue straggler stars are intriguing objects that seem to defy the standard theory of single-star evolution. They manage to elongate their main-sequence lifetimes by acquiring mass either in a direct stellar collision or through mass transfer in a binary ...

Radial velocities of blue stragglers in M3
Publications of the Astronomical Society of the Pacific, 1983The authors have obtained 1 A resolution spectra of five blue stragglers in M3 all with mv ≥ 17.3 using the MMT spectrograph and photon-counting Reticon. The spectra cover the range 4580 A to 5450 A, and except for Hβ are devoid of strong features. From measurements of the Hβ lines in the five blue stragglers and three velocity standards the authors ...

Blue Straggler Stars: Setting up a Dynamical Clock for Open Clusters
Bulletin de la Société royale des sciences de LiègeBlue straggler stars are late bloomers that are bluer and brighter than the main sequence turnoff stars on a color-magnitude diagram of a cluster. Being a massive population compared to their other cluster siblings, their sedimentation level has been ...

The incidence of magnetism in blue and yellow straggler stars
Astronomy & AstrophysicsOur understanding of the generation of magnetic fields in intermediate-mass and massive OBA stars remains limited. Some theories have proposed that their magnetic fields could be a result of strong binary interactions, including stellar mergers.
