The Outermost Ejecta of Type Ia Supernovae
Masaomi Tanaka, Paolo A. Mazzali, Stefano Benetti +6
The properties of the highest velocity ejecta of normal Type Ia supernovae (SNe Ia) are studied via models of very early optical spectra of 6 SNe. At epochs earlier than 1 week bef…
The underluminous Type Ia Supernova 2005bl and the class of objects similar to SN 1991bg
S. Taubenberger, S. Hachinger, G. Pignata +24
Optical observations of the Type Ia supernova (SN Ia) 2005bl in NGC 4070, obtained from -6 to +66 d with respect to the B-band maximum, are presented. The photometric evolution is…
Exploring the spectroscopic diversity of Type Ia Supernovae
S. Hachinger, P. A. Mazzali, S. Benetti
The velocities and equivalent widths (EWs) of a set of absorption features are measured for a sample of 28 well-observed Type Ia supernovae (SN Ia) covering a wide range of propert…
