Mean-field interpretation of star-in-a-box simulations of red giants
Carolina A. Ortiz-Rodríguez, Axel Brandenburg, Petri J. Käpylä
Context: The origin of magnetic fields and the dynamo mechanism in red giants are still not fully understood. Aims: We aim to interpret the dynamo behaviour of global 3D simulation…
Eclipsing time variations in close binaries produced by azimuthal dynamo waves
Felipe H. Navarrete, Dominik R. G. Schleicher, Petri J. Käpylä +1
The nature of eclipsing time variations (ETVs) in post-common-envelope binaries (PCEBs) is still unknown. Circumbinary planets routinely fail the test of time and the Applegate mec…
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) t…
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…
Magnetohydrodynamic simulations of A-type stars: Long-term evolution of core dynamo cycles
J. P. Hidalgo, P. J. Käpylä, D. R. G Schleicher +2
Early-type stars have convective cores due to a steep temperature gradient produced by the CNO cycle. These cores can host dynamos, and the generated magnetic fields can be relevan…
