Abstract

We report on the spectroscopic analysis of a subset of the 37 low-z supernovae discovered in the Supernova Cosmology Project spring 1999 campaign. This subset consists of 17 Type Ia SNe with redshifts between 0.009 and 0.15. Each supernova has been followed spectroscopically from the discovery day (generally before maximum) through several weeks after maximum. In addition, the final spectrum of the host galaxy at the location of the supernova was taken one year later. Spectral diversities are quantified, e.g. for the over-luminous supernova SN 1999aa. The size of the sample allows us to study the temporal evolution of spectral features and to correlate these with the lightcurve shape. Related background and photometric analyses on this supernova dataset are presented in the talk by Aldering et al. and the poster by Regnault et al.
