Global 3D simulations of convection and dynamos in Red Giants
Carolina Ortiz-Rodríguez, Petri Käpylä, Juan Pablo Hidalgo +2
Understanding the internal dynamics of red giants is essential for studying angular momentum transport and magnetic field generation during stellar evolution. We present three-dime…
Connecting mean-field theory with dynamo simulations
Petri J. Käpylä
Mean-field dynamo theory, describing the evolution of large-scale magnetic fields, has been the mainstay of theoretical interpretation of magnetism in astrophysical objects such as…
Magnetorotational instability in a solar near-surface mean-field dynamo
Axel Brandenburg, Gustav Larsson, Fabio Del Sordo +1
We address the question whether the magnetorotational instability (MRI) can operate in the near-surface shear layer (NSSL) of the Sun and how it affects the interaction with the dy…
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…
