About

UEMHP is an ERC funded project that runs until 2024.

The project UEMHP aims to understand how the dynamo mechanism inside planetary cores generates the magnetic field. In present-day computer simulations, the fluid viscosity is orders of magnitude to large than what is correct for planets. Our aim is to correct this by creating a working computer code that correctly implements a novel theory for the dynamo process in which viscosity and inertia have negligible effects. The dynamos obtained in such simulations are likely to be different from previous computational dynamos and lead to a better understanding of self-sustained dynamos. It will allow us to explore new and until now unreachable regimes.
