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.

WOCS 4540: Detailed Analysis of a very Long Orbital Period Blue Straggler [PDF]

open access: goldThe Astrophysical Journal, 2023
WOCS 4540 is the longest orbital period ( P _orb = 3030 days) blue straggler star (BSS)—white dwarf (WD) pair in the old open cluster NGC 188. It also contains one of the most luminous BSS in the cluster.

BLUE STRAGGLERS AFTER THE MAIN SEQUENCE [PDF]

open access: yesThe 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 ...

Blue Stragglers: Spectra of Globular Clusters [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2009
AbstractThe integrated Balmer lines of unresolved stellar systems have been widely used as age indicators, since they are sensitive to the temperature of the main sequence turn-off. However, the existence of “non-canonical” stellar stages such as hot horizontal branch stars and blue straggler stars (BSSs) can lead to underestimations of the true ...

Characterization of the Blue Straggler Star Populations, through Statistical, Photometric, and Spectral Energy Distribution Analysis, in the Old Open Cluster: NGC 2243

open access: goldThe Astronomical Journal
We present a statistical, photometric, and spectral energy distribution (SED) analysis of the poorly studied old open cluster: NGC 2243, to characterize its blue straggler star (BSS) population.

Fast-rotating Blue Straggler Stars in the Globular Cluster NGC 3201

open access: yesThe 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]

open access: yesProceedings 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 ...
