Blue straggler stars in dwarf spheroidal galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Blue straggler star (BSS) candidates have been observed in all old dwarf spheroidal galaxies (dSphs), however whether or not they are authentic BSSs or young stars has been a point of debate. To both address this issue and obtain a better understanding of the formation of BSSs in different environments we have analysed a sample of BSS candidates in two

BLUE STRAGGLERS AFTER THE MAIN SEQUENCE [PDF]
The 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 ...

The Formation Rate of Blue Stragglers in 47 Tucanae [PDF]
The Astrophysical Journal, 2000 We investigate the effects of changes in the blue straggler formation rate in globular clusters on the blue straggler distribution in the color-magnitude diagram. We find that the blue straggler distribution is highly sensitive to the past formation rate.

Modeling blue stragglers in young clusters [PDF]
Research in Astronomy and Astrophysics, 2011 In this paper, a grid of the binary evolution models are calculated for the study of blue straggler (BS) population in intermediate age ($\log Age$=7.85-8.95) star clusters. The BS formation via mass transfer and merging is studied systematically using our models.

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

The Astrophysical JournalWe investigate barium (Ba) abundances in blue straggler stars (BSSs) in two open clusters, NGC 7789 (1.6 Gyr) and M67 (4 Gyr), as signatures of asymptotic-giant-branch (AGB) mass transfer.
