Starspot activity of HD 199178. Doppler images from 1994--2017
Thomas Hackman, Iya Ilyin, Jyri J. Lehtinen +4
Context. Studying the spots of late-type stars is crucial for distinguishing between the various proposed dynamo mechanisms believed to be the main cause of starspot activity. For…
Modelling supernova driven turbulence
Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Käpylä +2
High Mach number shocks are ubiquitous in interstellar turbulence. The Pencil Code is particularly well suited to the study of magnetohydrodynamics in weakly compressible turbulenc…
Effects of a subadiabatic layer on convection and dynamos in spherical wedge simulations
Petri J. Käpylä, Mariangela Viviani, Maarit J. Käpylä +2
We consider the effect of a subadiabatic layer at the base of the convection zone on convection itself and the associated large-scale dynamos in spherical wedge geometry. We use a…
Small-scale dynamos in simulations of stratified turbulent convection
Petri J. Käpylä, Maarit J. Käpylä, Axel Brandenburg
Small-scale dynamo action is often held responsible for the generation of quiet-Sun magnetic fields. We aim to determine the excitation conditions and saturation level of small-sca…
