Spin-up of a rapidly rotating star by angular momentum loss

Abstract
Can a rotating star spin up by radiating away its angular momentum? And if so, what can we infer about the properties of such a star? We show that the spin of a rapidly rotating star like a pulsar can indeed increase as it radiates away energy and angular momentum. For this to happen the adiabatic index governing the equation of state must be very close to 4/3 if the star is rotating uniformly. Otherwise the star must be rotating differentially.
