Predictions of gravity mode pulsations of collisional blue straggler stars in globular clusters

Astronomy & Astrophysics
Blue straggler stars (BSSs) are exotic objects, which, being the results of processes such as mass transfer, mergers, or collisions, are considered key objects in the study of their host clusters' dynamics.

Identification of Blue Straggler Stars Based on MultiScale Dilation and Attention Mechanisms

Publications of the Astronomical Society of the Pacific
Blue straggler stars (BSSs) serve as vital tracers for investigating the dynamics and evolution of stellar systems, owing to their relatively higher luminosities and effective temperatures.

A binary-related origin mediated by environmental conditions for blue straggler stars

Nature Communications
Blue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enhancement processes, involving binary evolution or stellar collisions.

Revisiting the Evidence for Double Sequences of Blue Straggler Stars in Globular Clusters

Astronomical Journal
Blue straggler stars (BSSs) are believed to form through mass transfer in binary systems or stellar collisions. The reported presence of double BSS sequences in some globular clusters (GCs) has been interpreted as evidence that these two formation ...

Blue Straggler Stars in Berkeley 18: A Multiwavelength Study of Their Physical Properties and Dynamical Evolution

Monthly notices of the Royal Astronomical Society
Berkeley 18 is an old open cluster in the outer Galactic disk that hosts a population of blue straggler stars (BSSs). We present a comprehensive multiwavelength analysis of its BSS population using Gaia DR3 astrometry, optical–infrared photometry, and ...
