Scientific paper

The effect of electron scattering on energy distribution in the continuous specturm of a supernova is investigated by solving the problem of radiation transfer in an extended envelope. A supernova envelope is treated as an isothermal sphere with matter density decreasing exponentially with distance from the center. The spectrophotometric gradient is determined as a function of the envelope parameters, and it is shown that the spectrophotometric temperature is much lower than the surface temperature. Changes in spectrophotometric temperature with time during the outburst of a supernova are examined.
