STELLAR RESEARCH

Task B: Stellar magnetism across the Hertzsprung-Russell (HR) diagram:

The purpose of task B is to model accurately stars that are either less or more massive than the Sun or younger or more evolved (RGB) in order to map in 3-D stellar magnetism and the HR diagram .

Task B1: Convection, differential rotation and magnetism in low mass red giant (RGB) stars

Task B2: Young Suns: magnetism of fastly rotating stars, activity vs rotation scaling law

Task B3: A stars: magnetism in core convection of massive stars and interaction with magnetism in radiative envelope

Task B4: K stars: convection and magnetism in deep convection shell for low mass stars

Task B5: Introduction of averaged profiles and physical quantities deduced from 3-D simulations into 1D stellar evolution models and 2-D mean field stellar dynamo models
