Abstract:	Rotochemical heating originates in a departure from beta equilibrium in a rotating neutron star due to spin-down compression, the effect being strongest for millisecond pulsars (MSPs). The main consequence is the evolution in ~ 108 yr to a quasi-stationary state, in which the surface temperature depends only on the current spin-down power dE/dt = IΩ(dΩ/dt). Assuming no superfluidity, we find that the surface temperature is related to the spin-down power in the form of a power law. Moreover, the exponent depends only on the neutrino emission process assumed. Our simulations agree well with the recent detection of possible UV thermal radiation from a millisecond pulsar (Kargaltsev, Pavlov & Romani 2004, ApJ, 602, 327).
