Runaway OB Stars in the Small Magellanic Cloud III. Updated Kinematics and Insights on Dynamical vs. Supernova Ejections

Grant D. Phillips, M. S. Oey, Maria Cuevas +2

We use the kinematics of field OB stars to estimate the frequencies of runaway stars generated by the dynamical ejection scenario (DES), the binary supernova scenario (BSS), and th…
