From wikipedia(http://en.wikipedia.org/wiki/Supernova) :-
"A long-standing puzzle surrounding Type II supernovae is why the compact object remaining after the explosion is given a large velocity away from the epicentre; pulsars, and thus neutron stars, are observed to have high velocities, and black holes presumably do as well, although they are far harder to observe in isolation. The initial impetus can be substantial, propelling an object of more than a solar mass at a velocity of 500 km/s or greater. This indicates an asymmetry in the explosion, but the mechanism by which momentum is transferred to the compact object remains a puzzle."
My Question:- Could the remnant compact high-velocity object simply be the surviving member of a binary pair, flying off at a tangent from the original locality after the companion star has blown away in a supernova?
