A binary origin for ‘blue stragglers’ in globular clusters [PDF]

open access: yesNature, 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]

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. Two main theoretical scenarios (collisions and mass transfer) have been suggested to explain their formation, although ...

Radial velocities of blue stragglers in M3

Publications of the Astronomical Society of the Pacific, 1983
The authors have obtained 1 A resolution spectra of five blue stragglers in M3 all with mv ≥ 17.3 using the MMT spectrograph and photon-counting Reticon. The spectra cover the range 4580 A to 5450 A, and except for Hβ are devoid of strong features. From measurements of the Hβ lines in the five blue stragglers and three velocity standards the authors ...

Allan Sandage: Blue Stragglers

2021
One of the more recent stellar discoveries was made by noticing something out of place in globular cluster Messier 3 (M3) (Fig. 19.1).

Binary population synthesis for blue stragglers

Astrophysics and Space Science, 2010
In this talk, we will simply show the consequences of binary population synthesis for blue stragglers, such as the integrated spectral energy distribution (ISED), the color-magnitude diagram, the specific frequency, and the influences on colors. Blue stragglers have been found in all stellar populations and they are an important population component in
