A new, Gaia-based, catalogue of blue straggler stars in open clusters [PDF]
Astronomy & Astrophysics, 2021 Context. Blue straggler stars are exotic objects present in all stellar environments whose nature and formation channels are still partially unclear. They seem to be particularly abundant in open clusters (OCs), thus offering a unique chance to tackle ...

UOCS VII. Blue Straggler Populations of Open Cluster NGC 7789 with UVIT/AstroSat [PDF]
, 2022 NGC 7789 is a $\sim$1.6 Gyr old, populous open cluster located at $\sim$2000 pc. We characterize the blue straggler stars (BSS) of this cluster using the Ultraviolet (UV) data from the UVIT/AstroSat.

Blue Straggler Stars in open clusters using Gaia: Dependence on cluster parameters and possible formation pathways [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Blue straggler stars (BSSs) are the most massive stars in a cluster formed via binary or higher-order stellar interactions. Though the exact nature of such formation scenarios is difficult to pin down, we provide observational constraints on the ...

Nonstandard Modeling of a Possible Blue Straggler Star, KIC 11145123 [PDF]
Astrophysical Journal, 2021 Nonstandard modeling of KIC 11145123, a possible blue straggler star, has been asteroseismically carried out based on a scheme to compute stellar models with the chemical compositions in their envelopes arbitrarily modified, mimicking the effects of some

BLUE STRAGGLERS AFTER THE MAIN SEQUENCE [PDF]
The Astrophysical Journal, 2009 We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases. We found that the blue straggler progeny populate the colour-magnitude diagram slightly blueward of the red giant branch and between 0.2 and 1 ...

The fractions of post-binary-interaction stars and evolved blue straggler stars on the red giant branch of globular clusters [PDF]
Research in Astronomy and Astrophysics, 2021 The red giant branch (RGB) of globular clusters (GCs) is home to some exotic stars, which may provide clues on the formation of multiple stellar populations in GCs. It is well known that binary interactions are responsible for many exotic stars. Thus, it

Primordial binary evolution and blue stragglers [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractBlue stragglers have been found in all populations. They are important in both stellar evolution and stellar population synthesis. Much evidence shows that blue stragglers are relevant to primordial binaries. Here, we summarize the links between binary evolution and blue stragglers, describe the characteristics of blue stragglers originating ...

The Astrophysical Journal, 2023 We have used the “dynamical clock” to measure the level of dynamical evolution reached by three Galactic globular clusters (namely, NGC 3201, NGC 6316, and NGC 6440).
