Description
This lecture covers the topics of MHD waves, instabilities in stellar astrophysics, and magnetoconvection. It discusses the linear analysis of magnetoconvection, selected MHD instabilities, and the impact of temperature gradients on volume expansion. The lecture also explores the Rayleigh number, Chandrasekhar numbers, and the role of B-fields in inhibiting convection. The instructor explains the nonlinear evolution of magnetoconvection, Sunspots, and the magnetic buoyancy effect. Additionally, the lecture delves into the connection between magnetic helicity and topology, emphasizing the conservation laws and the application to cosmology.
