The incidence of magnetism in blue and yellow straggler stars [PDF]

Astronomy & Astrophysics
Our 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.

Observations of blue straggler stars in globular clusters [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractBlue stragglers stars (BSS) define a sparsely populated sequence extending to higher luminosity than the turnoff point of normal main sequence stars in the color magnitude diagrams of stellar aggregates, thus mimicking a rejuvenated (more massive) stellar population. The nature of these stars has been a puzzle for many years and their formation

The new detection of blue straggler stars in 50 open clusters using Gaia DR3 [PDF]

Astronomy & Astrophysics, 2023
The particularly abundant presence of blue straggler stars (BSS) in Galactic open clusters offers favorable conditions for detailed studies on the statistical properties and the origin of the blue straggler population.

UOCS-XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat [PDF]

Monthly notices of the Royal Astronomical Society, 2023
We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine learning-based algorithm, ML-MOC, on Gaia DR3 data, we find 546 sources as cluster members.

The Multiple Origin of Blue Straggler Stars: Theory vs. Observations [PDF]

, 2014
In this chapter we review the various suggested channels for the formation and evolution of blue straggler stars (BSSs) in different environments and their observational predictions.

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

Discovery of a Double Sequence of Blue Straggler Stars in the Core-collapsed Globular Cluster NGC 6256 [PDF]

Astrophysical Journal, 2022
We used a combination of high-resolution optical images acquired with the Hubble Space Telescope and near-IR wide-field data to investigate the stellar density profile and the population of blue straggler stars (BSSs) in the Galactic globular cluster NGC
