Abstract:
We investigate line formation processes in Type IIb supernovae (SNe)
from 100 to 500 days post-explosion using spectral synthesis
calculations. The modelling identifies the nuclear burning layers and
physical mechanisms that produce the major emission lines, and the
diagnostic potential of these. We compare the model calculations with
data on the three best observed Type IIb SNe to-date - SN 1993J,
SN 2008ax, and SN 2011dh.
