Lecture 1: Rotation of Rigid Body
... unexpected speedup called a glitch. One explanation is that a glitch occurs when the crust of the neutron star settles slightly, decreasing the moment of inertia about the rotation axis. A neutron star with angular speed 0=70.4 rad/s underwent such a glitch in October 1975 that increased its angula ...
