How Neutron Stars Get Their Kicks: Cornell Researcher Poses Rocket Theory

Summary:
A newly formed neutron star is sent whizzing along at several hundred miles a second, sometimes more than 600 miles a second, compared with the original star, which typically was dawdling along at a few tens of miles a second. Apparently, the neutron star is "kicked" at birth. But what is the origin of this kick that causes the furious acceleration of the newly born neutron star?

ROCHESTER, N.Y. -- When a massive star runs out of nuclear fuel something extraordinary happens in the space of a few seconds: The star's core collapses from a radius of 1,000 miles into a tight, dense ball -- a neutron star -- with a radius of only 10 miles, and then with fearsome energy the massive stellar "envelope," equal to about 10 solar masses, is ejected into outer space.
