Abstract
SPECTRA of type I supernovae show broad emission bands, none of which has been satisfactorily explained1. Seddon2 has proposed that the structure in the visible spectrum be regarded as broad absorption bands on a more intense continuum. The absorption bands could be produced by clouds of dust surrounding the star. On this viewpoint several supernovae absorption features fall near some of the much narrower unidentified absorption bands arising in the interstellar medium. This article reports an application of this new interstellar band explanation to supernovae spectra interpreted in terms of absorption features. The more intense background used to obtain the supernovae absorption will be discussed after a brief presentation of the proposed absorption band origin.
