Objective Extensive theoretical studies of the fundamental properties of superdense matter in neutron star interiors are planned with the aim of modelling the thermal radiation from neutron stars and interpretating recent observational data supplied by the ROSAT X-ray observatory. Theoretical analysis of physical properties of matter in neutron star cores (neutrino generation mechanisms with proper account of nucleon superfluidity) will be performed, as well as subsequent numerical simulations of neutron star cooling to relate the parameters of stellar interiors to the properties of the thermal radiation observed. Theoretical studies of the subphotospheric layers of neutron stars with strong magnetic fields and of radiative opacities in the photosphere will be carried out to update significantly the numerical radiative transfer code. A grid of models of neutron star photospheres with various effective surface temperatures, gravities and magnetic fields, will be calculated and used for interpretation of the ROSAT observations of thermal radiation from a number of pulsars (PSR 0656+14, PSR 1055-52, PSR 1999+10, PSR J0437-4715, Crab, Geminga). It is expected that valuable new information of astrophysical and astronomical importance will be obtained on the parameters of neutron stars: masses, radii, magnetic fields, distances, etc., and on fundamental properties of superdense matter in their cores: equation of state, nuclear composition, superfluid state of baryons.
