| Abstract: |
All explosion models proposed up to date for thermonuclear supernovae involve
carbon-oxygen detonations at low densities. At these densities Si and O time-scales of burning become comparable or longer than hydrodynamical time-scales
and only C burning may occur (C-detonation). Therefore, burning is not complete
and intermediate mass elements are produced as observed in the near-maximum
spectra. However, previous analysis of the structure and
stability of detonations in thermonuclear supernovae did not consider incomplete
detonations with partial energy release. In this work we find that, in contrast
with complete detonations, C-detonations are highly unstable and may quench at low
densities. Implications for supernova modelling and observations are
discussed. |
