Nuclear reactions occurring at high densities in the crust of an accreting neutron star efficiently heat the inner crust and core to temperatures > 10^8 K. When accretion halts, as in a transient accretor, the envelope relaxes to a thermal equilibrium set by the flux from the hot core. For the time-averaged accretion rates typical of low-mass X-ray transients, this luminosity is ~1033 erg/s and agrees with many observations of transient neutron stars in quiescence. After the crust reaches its equilibrium thermal profile, the luminosity and effective temperature will remain steady over timescales much longer than the typical outburst recurrence time.
