Binary evolution and double sequences of blue stragglers in globular clusters

Proceedings of the International Astronomical Union, 2018
Binary evolution can produce different blue-straggler binaries, for example, blue stragglers with a bright, red component, or with a faint, blue component.

Blue Stragglers and Friends: Initial Evolutionary Pathways in Close Low-Mass Binaries

Annual Review of Astronomy and Astrophysics
The scope of this review is the first stage in the evolution of close binary stars having components with M < 2 M⊙. An observational taxonomy for the products of such binary evolution is provided in the framework of dwarfs (blue straggler stars), giants (

Beyond the main sequence: Binary evolution pathways to blue stragglers in the Gaia era. I. Galactic open and globular clusters

Astronomy & Astrophysics
The study of blue straggler stars (BSSs) provides insight into the mechanisms of stellar mass exchange during binary stellar evolution and the complex gravitational interactions within dense stellar systems. In combination, they enhance our understanding

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 Evolution: Roche Lobe Overflow and Blue Stragglers

, 2014
One of the principal mechanisms that is responsible for the origin of blue stragglers is mass transfer that takes place while one of the binary companions overfills its Roche lobe.

Blue Stragglers in Globular Clusters: Observations, Statistics and Physics

, 2014
This chapter explores how we might use the observed statistics of blue stragglers in globular clusters to shed light on their formation. This means we will touch on topics also discussed elsewhere in this book, such as the discovery and implications of ...

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

Are All Blue Stragglers Ap Stars?

International Astronomical Union Colloquium, 1976
SummaryA list of open clusters with blue stragglers studied for Ap characteristics is presented. In addition to previously published results new spectroscopic data are given of blue stragglers in the open cluster IC 4756 derived from ESO spectrograms taken in 1973. Preliminary conclusions concerning the status of Ap stars and blue stragglers are drawn.
