ADI - Anti-diffusive dynamics: from sub-cellular to astrophysical scales

I will discuss two examples from astrophysics in which composition gradients and convection interact to give anti-diffusive dynamics: the evolving composition profile of Jupiter’s interior and crystallization-driven fingering convection in white dwarfs. They are motivated by recent observational results – the inferred density profile of Jupiter from the Juno mission, and new results on cooling white dwarfs from Gaia. For Jupiter, I will show results from Boussinesq simulations of penetrative convection and layer formation at Prandtl number
