Spectral luminosity indicators in SNe Ia - Understanding the R(SiII) line strength ratio and beyond
Stephan Hachinger, Paolo A. Mazzali, Masaomi Tanaka +2
SNe Ia are good distance indicators because the shape of their light curves, which can be measured independently of distance, varies smoothly with luminosity. This suggests that SN…
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…
