We present numerical simulations of the runaway fractions e xpected amongst O and WolfRayet star populations resulting from stars ejected from bi naries by the supernova of the companion. Observationally the runaway fraction for both t ypes of star is similar, prompting the explanation that close dynamical interactions are the m ain cause of these high… CONTINUE READING
