Abstract

Toward the next generation of evolutionary computations and application to white dwarfs

We present our ongoing efforts into producing a completely new and modern implementation of an evolutionary code geared specifically toward stellar seismology and spectral/chemical evolution. A specificity of our code is that evolutionary computations are producing complete models of stars: down from the core up to, and including, the atmosphere. Sophisticated transport mechanisms are included: time-dependent convection, over- and under-shooting, semi-convection, thermohaline mixing, gravitational settling, simultaneous multi-elements diffusion, thermal and turbulent diffusion, winds and accretion events. Radiative support of elements is currently under implementation. We also present DA and DB evolutionary tracks along with their spectral type transformations.
