Abstract:	We have studied blue straggler stars (BSS) in a variety of Milky Way satellites: outer halo globular clusters, classical dwarf galaxies and the newly found ultra-faint dwarf galaxies and found BSS to be ubiquitous among all of them. Moreover, we study the likelihood that our BSS candidates correspond to young stars by analysing correlations between BSS frequencies and satellite parameters (such as absolute magnitude and collision time), and BSS distributions compared to those of simulated young stars. We find that the observed BSS seem to be genuine and likely formed by mass transfer in close binaries.
