Ecology of Blue Straggler Stars

open access: yesAstrophysics and Space Science Library, 2015
The existence of blue straggler stars (BSS), which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution, as such stars should have exhausted their nuclear fuel and evolved long ago to become cooling white dwarfs.

Chemical composition of a palomar 12 blue straggler

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
ABSTRACT With the equivalent area of a 16-m telescope, ESPRESSO in 4UT mode allows to inaugurate high resolution spectroscopy for solar-type stars belonging to extragalactic globular clusters. We determine the chemical composition of an extragalactic blue straggler (BS).

Fast rotating blue stragglers prefer loose clusters

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.

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 ...

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 ...
