Blue Straggler Stars beyond the Milky Way. II. A Binary Origin for Blue Straggler Stars in Magellanic Cloud Clusters [PDF]
The Astrophysical Journal, 2018 Abstract We have analyzed populations of blue straggler stars (BSSs) in 24 Magellanic Cloud (MC) star clusters using multi-passband Hubble Space Telescope images. We compiled a homogeneous BSS database, containing both traditional and evolved BSSs.

Blue straggler stars in dwarf spheroidal galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Blue straggler star (BSS) candidates have been observed in all old dwarf spheroidal galaxies (dSphs), however whether or not they are authentic BSSs or young stars has been a point of debate. To both address this issue and obtain a better understanding of the formation of BSSs in different environments we have analysed a sample of BSS candidates in two

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).

M67 Blue Stragglers with High-resolution Infrared Spectroscopy
The Astronomical Journal, 2023 We report on the first detailed infrared chemical analysis of five binary members (S277, S997, S975, S1031, and S1195) in the open cluster M67 (NGC 2682).

A Wide Metallicity Range for Gyr-old Stars in the Nuclear Star Cluster
The Astrophysical Journal Letters, 2023 We report metallicities for three ∼Gyr-old stars in the Milky Way nuclear star cluster (NSC) using high-resolution near-infrared spectroscopy. We derive effective temperatures from a calibration with Sc line strength, which yields results in good ...

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

On the Variability of Blue Straggler Stars in the Globular Cluster M53 [PDF]
Journal of Astronomy and Space Sciences, 1998 We present the results of a search for photometric variable blue straggler stars (BSSs) in the globular cluster M53. Six of the 151 probable BSSs are identified as variable candidates based on the robust variable star detection technique of Welch ...
