MESA AND NUGRID: A FRAMEWORK FOR MODELLING OF NOVAE EXPLOSIONS AND NUCLEOSYNTHESIS

Novae

 

We present a new framework for 1D numerical simulations of novae explosions and nucleosynthesis. It combines the powers of the state-of-the-art MESA stellar evolution code and NuGrid post-processing nucleosynthesis code. It is designed to be used by any interested researcher or student. To make it easy to run the codes and their visualization tools by a non-expert, the framework will include user- friendly shell scripts and detailed instructions on how to use them. It is shown that our framework allows to compute the evolution of CO novae through several consecutive explosions. The framework will soon be extended to include ONe novae and mixing between the accreted envelope and underlying white dwarf.
