Spectrum formation in SN Ia
Posted: Wed Oct 12, 2011 5:43 pm
I tried to summarize what I understood about the spectrum formation and evolution in type Ia supernovae.
Also are presented first results of velocity measurements of the ARAS campaign spectra.

SN 2011fe is now about 1 month after maximum light (10-09-2011), it should be at the begining of the "nebular phase". New spectra would be welcome in order to finalize our observing campaign.
