Effects of rotation and surface forcing on deep stellar convection zones
Petri J. Käpylä
The canonical undestanding of stellar convection has recently been put under doubt due to helioseismic results and global 3D convection simulations. This "convective conundrum" is…
Simulations of solar and stellar dynamos and their theoretical interpretation
Petri J. Käpylä, Matthew K. Browning, Allan Sacha Brun +2
We review the state of the art of three dimensional numerical simulations of solar and stellar dynamos. We summarize fundamental constraints of numerical modelling and the techniqu…
Simulations of dynamo action in slowly rotating M dwarfs: Dependence on dimensionless parameters
C. A. Ortiz-Rodríguez, P. J. Käpylä, F. H. Navarrete +4
The aim of this study is to explore the magnetic and flow properties of fully convective M dwarfs as a function of rotation period Prot and magnetic Reynolds ReM and Prandlt number…
Effects of the centrifugal force in stellar dynamo simulations
Felipe H. Navarrete, Petri J. Käpylä, Dominik R. G. Schleicher +1
The centrifugal force is often omitted from simulations of stellar convection either for numerical reasons or because it is assumed to be weak compared to the gravitational force.…
