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 ...

Field blue straggler stars: discovery of white dwarf companions to blue metal-poor stars using UVIT/AstroSat [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 Blue metal-poor (BMP) stars are the main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters.

Photometric variability of blue straggler stars in M67 with TESS and K2 [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 Blue straggler stars (BSSs) are formed through mass transfers or mergers in binaries. The recent detections of white dwarf (WD) companions to BSSs in M67 suggested a mass transfer pathway of formation. In search of a close companion to five BSSs in M67

Blue Stragglers and Friends: Initial Evolutionary Pathways in Close Low-Mass Binaries
Annual Review of Astronomy and AstrophysicsThe scope of this review is the first stage in the evolution of close binary stars having components with M < 2 M⊙. An observational taxonomy for the products of such binary evolution is provided in the framework of dwarfs (blue straggler stars), giants (

The Clusters AgeS Experiment (CASE). Variable stars in the field of the globular cluster NGC 6362
, 2017The field of the globular cluster M22 (NGC 6656) was monitored between 2000 and 2008 in a search for variable stars. $BV$ light curves were obtained for 359 periodic, likely periodic, and long-term variables, 238 of which are new detections.

Rotational velocities of blue straggler stars in the globular cluster M 55 [PDF]
Astronomy and AstrophysicsBy using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured the radial and rotational velocities of 115 stars in the Galactic globular cluster M55.

A Catalog of New Blue Stragglers in Open Clusters with Gaia DR3
Research in Astronomy and AstrophysicsThe high-precision Gaia Data Release 3 (DR3) enables the discovery of numerous open clusters (OCs) in the Milky Way, providing an excellent opportunity to search for blue straggler stars in OCs and investigate their formation and evolution in these ...

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 ...

We 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.
