The maximum possible velocity of dynamically ejected runaway stars

A total of 9550 point particle binary-binary scattering experiments have been performed in order to estimate the maximum possible velocity (MPV) of dynamically ejected runaway stars. It is found that the MPV for a low-mass companion ejected from a binary-binary interaction is roughly the escape velo...

description	A total of 9550 point particle binary-binary scattering experiments have been performed in order to estimate the maximum possible velocity (MPV) of dynamically ejected runaway stars. It is found that the MPV for a low-mass companion ejected from a binary-binary interaction is roughly the escape velocity from the surface of the most massive star involved in the interaction. The MPV at infinity that the most massive star involved in an interaction can attain is roughly half the escape velocity from the star's surface. (C.D.)
