| Abstract: | The time-dependent equation of radiative transfer is solved exactly and in then-th Gaussian approximation.The atmosphere is plane-parallel and semi-infinite; isotropic scattering is assumed, but the boundary condition at  =0 is arbitrary.The results are used to investigate a suggested mechanism for the origin of the secondary pulses in CP 0950; it is found that a binary system of neutron stars can indeed explain formation, time delay and intensity of the observed interpulse. |
