Accreting neutron stars and deep crustal heating

Deep crustal heating was proposed as an explanation of the observed quiescent emission of the X-ray transients. I will present new model of the deep crustal heating based on the extended Thomas-Fermi method used for the calculation of the properties of neutron star crust. The location of the energy sources in the crust and the energy release due to non-equilibrium reactions are main parameters determining the cooling of the neutron star in the accreting system in quiescent phase. The dependence of these parameters on the assumed microscopic model of dense matter in the crust is discussed.
