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.

Unveiling Bifurcated Blue Straggler Sequences in NGC 2173: Insights from Binary Evolution [PDF]
The Astrophysical JournalIdentifying bifurcated blue straggler (BS) sequences in color–magnitude diagrams (CMDs) of star clusters has long been regarded as a powerful diagnostic for distinguishing different BS formation mechanisms.

Characterization of Blue and Yellow Straggler Stars of Berkeley 39 [PDF]
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

Building Blue Stragglers with Stellar Collisions [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product with an (evolved) main sequence star, or assume that the collision product was completely mixed during the collision.It is known from hydrodynamical simulations of ...

Discovery of a Barium Blue Straggler Star in M67 and “Sighting” of Its White Dwarf Companion
The Astrophysical Journal LettersWe report the discovery of a barium blue straggler star (BSS) in M67, exhibiting enhancements in slow neutron-capture ( s -)process elements. Spectroscopic analysis of two BSSs (WOCS 9005 & WOCS 1020) and four stars located near the main-sequence turn ...

Blue Stragglers: Spectra of Globular Clusters [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractThe integrated Balmer lines of unresolved stellar systems have been widely used as age indicators, since they are sensitive to the temperature of the main sequence turn-off. However, the existence of “non-canonical” stellar stages such as hot horizontal branch stars and blue straggler stars (BSSs) can lead to underestimations of the true ...

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 ...
