ACCRETION ONTO A NEUTRON-STAR IN THE PRES ENCE OF AN INTENSE RADIATION

A complete system of quasi-hydrodynamic equations is derived describin g the interaction of plasma with intense radiation. With the aid of th e system the spherically symmetric Eddington accretion onto a neutron star is studied. The expressions describing the spatial distributions of densities, temperatures, and fluxes of plasma and photon gas are fo und. The total picture of flow, including all the numerical values obt ained, depends on the only external parameter being the relative proxi mity to the Eddington limit.
