OBS

Supernova seem to divide into two classes: type I and type II. Type I exhibit the presence of heavy elements in their spectra and relatively little hydrogen while type II exhibits primarily hydrogen. The differentiation is real and probably arises from differences in the masses of the original stars.

OBS

Dans le voisinage du maximum ces supernovae [du type I] ont un spectre continu dans lequel on ne discerne aucune raie. Par la suite on voit apparaître des bandes d'émission très larges dont la position ne coïncide avec aucune des raies spectrales connues. La largeur de ces bandes correspond à la dilatation des gaz à la vitesse allant jusqu'à 6000 km/s. L'intensité, la structure et la position des bandes changent souvent en fonction du temps. Six mois après le maximum on voit apparaître des bandes qu'on identifie au spectre de l'oxygène neutre.
