The solar dynamo begins near the surface
Geoffrey M Vasil, Daniel Lecoanet, Kyle Augustson +5
The Sun's magnetic dynamo cycle features a distinct pattern: a propagating region of sunspot emergence appears around 30 degrees latitude and vanishes near the equator every 11 yea…
The Puzzling Structure of Solar Convection: Window into the Dynamo
Nicholas A. Featherstone, Kyle C. Augustson, Jonathan M. Aurnou +25
The operation of the solar dynamo, with all of its remarkable spatio-temporal ordering, remains an outstanding problem of modern solar physics. A number of mechanisms that might pl…
Powering Stellar Magnetism: Energy Transfers in Cyclic Dynamos of Sun-like Stars
Allan Sacha Brun, Antoine Strugarek, Quentin Noraz +5
We use the ASH code to model the convective dynamo of solar-type stars. Based on a series of 15 3-D MHD simulations spanning 4 bins in rotation and mass, we show what mechanisms ar…
Probing the internal magnetism of stars using asymptotic magneto-asteroseismology
Stéphane Mathis, Lisa Bugnet, Vincent Prat +3
Our knowledge of the dynamics of stars has undergone a revolution thanks to the simultaneous large amount of high-quality photometric observations collected by space-based asterose…
The impact of a fossil magnetic field on dipolar mixed-mode frequencies in sub- and red-giant stars
L. Bugnet, V. Prat, S. Mathis +5
Stars more massive than M are known to develop a convective core during the main-sequence: the dynamo process triggered by this convection could be the origin of…
Lithium depletion and angular momentum transport in solar-type stars
T. Dumont, A. Palacios, C. Charbonnel +4
Transport processes occurring in the radiative interior of solar-type stars are evidenced by the surface variation of light elements, in particular Li, and the evolution of their r…
