The impact of the chemical stratification of white dwarfs on the classification of classical novae.

Abstract (from CDS):

We analyze the impact of the initial abundances of the underlying white dwarf core on the nucleosynthesis accompanying classical nova outbursts, in the framework of hydrodynamic models of the explosion. Specifically, we take into account the chemical stratification of the white dwarf. It turns out that the presence of a thick CO buffer on top of the ONe-rich core, as results from detailed calculations of previous evolution of the progenitor star, may lead to significant amounts of both 7Li and 26Al, after an outburst that, because of the lack of neon isotopes in the ejecta, would be misclassified as a non-neon nova (i.e., CO nova).
