Magnetism, dynamo action and the solar-stellar connection

AS Brun, MK Browning - Living Reviews in Solar Physics, 2017 - Springer
The Sun and other stars are magnetic: magnetism pervades their interiors and affects their
evolution in a variety of ways. In the Sun, both the fields themselves and their influence on …

Convective boundary mixing in main-sequence stars: theory and empirical constraints

EH Anders, MG Pedersen - Galaxies, 2023 - mdpi.com
The convective envelopes of solar-type stars and the convective cores of intermediate-and
high-mass stars share boundaries with stable radiative zones. Through a host of processes …

A study of convective core overshooting as a function of stellar mass based on two-dimensional hydrodynamical simulations
