OSTI ID:10136322
The hypothesis that the blue stragglers in the dwarf spheroidal galaxie have a collisional origin is considered. If all of the dark matter in these galaxies is in the form of low-mass stars and the binary frequency is {approx_equal} 50%, then it is quite possible that {approx_equal} 10% to 20% of their blue stragglers have been produced by physical stellar collisions.
