Fast rotating blue stragglers prefer loose clusters [PDF]

open access: yesNature Communications, 2023
Blue stragglers are anomalously luminous core hydrogen-burning stars formed through mass-transfer in binary/triple systems and stellar collisions. Their physical and evolutionary properties are largely unknown and unconstrained.

FORMATION AND EVOLUTION OF BLUE STRAGGLERS IN 47 TUCANAE [PDF]

open access: bronzeThe Astrophysical Journal, 2016
Blue stragglers (BSS) are stars whose position in the color–magnitude diagram (CMD) places them above the main sequence (MS) turn-off (TO) point of a star cluster.

M67 Blue Stragglers with High-resolution Infrared Spectroscopy [PDF]

open access: yesThe 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).

UOCS-IX. AstroSat/UVIT Study of the Open Cluster NGC 2818: Blue Stragglers, Yellow Stragglers, Planetary Nebula, and their Membership [PDF]

open access: yesThe Astrophysical Journal, 2023
We present the first far-UV (FUV) imaging results of the intermediate-age Galactic open cluster NGC 2818 that has a planetary nebula (PN) within the field using images taken from the Ultra Violet Imaging Telescope (UVIT) aboard AstroSat.

Precision analysis of NGC 2158 with Gaia DR3 [PDF]

open access: yesScientific Reports
This research uses the third edition of the Gaia Data Release (DR3) to re-investigate the open star cluster NGC 2158. We employed the pyUPMASK Python package and HDBSCAN algorithms to identify the cluster member stars. The key focus of this investigation

A chemical study of M67 candidate blue stragglers and evolved blue stragglers observed with APOGEE DR14 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
Within the variety of objects populating stellar clusters, blue straggler stars (BSSs) are among the most puzzling ones. BSSs are commonly found in globular clusters, but they are also known to populate open clusters of the Milky Way.

A catalog of new blue stragglers in open clusters with Gaia DR3 [PDF]

open access: greenResearch in Astronomy and Astrophysics
The 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 ...

MOCK OBSERVATIONS OF BLUE STRAGGLERS IN GLOBULAR CLUSTER MODELS [PDF]

open access: bronze, 2013
We created artificial color–magnitude diagrams of Monte Carlo dynamical models of globular clusters and then used observational methods to determine the number of blue stragglers in those clusters.
