CN 1987A: the origin of the blue shift of the Hα emission
Description
A simple modification of the standard model of line formation in the expanding supernova envelope at the photospheric phase is proposed. Namely, the effect of diffuse reflection of quanta from the photosphere is taken into account. This effect supposedly have to take place under dominant role of the electron scattering in the continuum. Blue shift of the maximum of Hα emission SN 1987A is shown to be well reproduced when diffuse reflection is taken into account
