Blue Stragglers After the Main Sequence [PDF]

The Astrophysical Journal, 2008
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.

On the triple origin of blue stragglers [PDF]

The Astrophysical Journal, 2009
Blue straggler stars (BSSs) are stars observed to be hotter and bluer than other stars with the same luminosity in their environment. As such they appear to be much younger than the rest of the stellar population. Two main channels have been suggested to

Models of Individual Blue Stragglers [PDF]

, 2014
This chapter describes the current state of models of individual blue stragglers. Stellar collisions, binary mergers (or coalescence), and partial or ongoing mass transfer have all been studied in some detail.

Building Blue Stragglers with Stellar Collisions [PDF]

Proceedings of the International Astronomical Union, 2007
The evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product with an (evolved) main sequence star, or assume that the collision ...

Blue Straggler Formation in Clusters [PDF]

AIP Conference Proceedings, 2010
Blue stragglers are thought to be formed from the merger or coalescence of two stars, but the details of their formation in clusters has been difficult to disentangle.

A spectroscopic study of the blue stragglers in M67 [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
Based on spectrophotometric observations from the Guillermo Haro Observatory (Cananea, Mexico), a study of the spectral properties of the complete sample of 24 blue straggler stars (BSs) in the old Galactic open cluster M67 (NGC 2682) is presented.

Formation Channels for Blue Straggler Stars [PDF]

, 2014
In this chapter we consider two formation channels for blue straggler stars: 1) the merger of two single stars via a collision, and 2) those produced via mass transfer within a binary.

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 ...
