Abstract
Fluid layers in planets are ubiquitous, either in the form of metallic cores, oceans or atmospheres. In this class we will focus on the planetary cores and subsurface oceans fluid dynamics and see how one can probe remotely these fluid layers by observing the variations of planets rotation or magnetic field.
Objective
-Understand how observing the rotation and magnetic signature of planets can help probe their internal structure. -Understand the basic mechanisms by which angular momentum and heat is exchanged between the fluid and the solid layers. -Understand how and where dissipation occurs. -Identify the challenges ahead of us to make progress in this field.
Content
-Introduction to rotating fluid dynamics: Geostrophic flows / inertial modes / inertial waves / Instabilities and turbulence -Introduction to thermal and compositional convection, with and without rotation. -Application to planets: Mantle convection / Earth's core convection / Precession of the Earth's and Lunar core.
