Fast rotating blue stragglers prefer loose clusters [PDF]
Nature 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.

A binary-related origin mediated by environmental conditions for blue straggler stars [PDF]
Nature CommunicationsBlue 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.

A binary origin for ‘blue stragglers’ in globular clusters [PDF]
Nature, 2009 Blue stragglers in globular clusters are abnormally massive stars that should have evolved off the stellar main sequence long ago. There are two known processes that can create these objects: direct stellar collisions and binary evolution. However, the relative importance of these processes has remained unclear.

A chemical study of M67 candidate blue stragglers and evolved blue stragglers observed with APOGEE DR14 [PDF]
Monthly 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. Two main theoretical scenarios (collisions and mass transfer) have been suggested to explain their formation, although ...

Fast-rotating Blue Straggler Stars in the Globular Cluster NGC 3201
The Astrophysical Journal, 2023 We used high-resolution spectra acquired with the Magellan Telescope to measure radial and rotational velocities of approximately 200 stars in the Galactic globular cluster NGC 3201.

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 ...

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 ...
