Mid-Term Report Summary - CHASM (Convective Heat Transport and Stellar Magnetism)

Convection and magnetism are ubiquitous in stars and planets. All stars transport some of their energy by convective motions; so do many substellar objects (like brown dwarfs and planets). Magnetism is likewise common to many of these objects: the most famous example is our Sun, whose 22-year cycle of magnetic activity affects our society in myriad ways. Broadly, the CHASM project seeks to develop models of the magnetic fields of stars and planets. We are essentially trying to understand how these fields are built by the convection, and what effects they have on the overall structure and evolution of these objects. We are using a multi-pronged approach that includes both global-scale 3-D magnetohydrodynamic calculations — which model phenomena in great detail but can only capture a limited period in a star’s life — together with more localised simulations and analytical (or semi-analytical) theory.
