Scientific paper

A young pulsar cools rapidly by neutrino emission. The resulting thermal contraction leads to spin-up in the earliest epochs when the effect dominates over spin-down by magnetic dipole radiation. This initial spin-up may last several years. The characteristic time dependence of the neutrino luminosity can also dominate in the second derivative of the rotation rate for as long as thousands of years with favorable initial conditions.
