Mean-field interpretation of star-in-a-box simulations of red giants
Carolina A. Ortiz-RodrÃguez, Axel Brandenburg, Petri J. Käpylä
The paper uses mean‑field dynamo models, constrained by differential rotation profiles from global 3D simulations, to explain how magnetic fields are generated and evolve in red gi…
effect in rotating hydrodynamic convection
P. J. Käpylä
Context: Rotating anisotropic convection generates differential rotation in stellar convection zones. Aims: The main aim is to compute the non-diffusive contribution ( effect)…
Shaping core dynamos in A-type stars: The role of dipolar fossil fields
J. P. Hidalgo, P. J. Käpylä, D. R. G Schleicher +2
Large-scale magnetic fields of Ap/Bp stars are stable over long timescales and have typically simple dipolar geometries, leading to the idea of a fossil origin. These stars are als…
Simulations of entropy rain-driven convection
P. J. Käpylä
Context: The paradigm of convection in solar-like stars is questioned based on recent solar observations. Aims: The primary aim is to study the effects of surface-driven entropy ra…
