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.
