Progress in atmospheres of X-ray bursting stars modeling

A new computer code for hot neutron star atmospheres modeling and computed extended set of model
atmospherses for various luminosities, surface gravities and chemical compositions are presented. In the
new code Compton scattering is taken into account with accurate fully relativistic angle-dependent
redistribution function. The computed models are compared with previously obtained models which employ
Kompaneets operator. A usage of new models for neutron star parameters deriving from the cooling stages
of X-ray bursts is discussed.
