Reynolds number dependence of Lyapunov exponents of turbulence and fluid particles
Itzhak Fouxon, Joshua Feinberg, Petri Käpylä +1
The Navier-Stokes equations generate an infinite set of generalized Lyapunov exponents defined by different ways of measuring the distance between exponentially diverging perturbed…
Star-in-a-box simulations of fully convective stars
Petri J. Käpylä
(abridged) Context: Main-sequence late-type stars with masses less than are fully convective. Aims: The goal is to study convection, differential rotation, and dynam…
Common dynamo scaling in slowly rotating young and evolved stars
Jyri J. Lehtinen, Federico Spada, Maarit J. Käpylä +2
One interpretation of the activity and magnetism of late-type stars is that these both intensify with decreasing Rossby number up to a saturation level, suggesting that stellar dyn…
Antisolar differential rotation of slowly rotating cool stars
G. Rüdiger, M. Küker, P. Käpylä +1
Rotating stellar convection transports angular momentum towards the equator, generating the characteristic equatorial acceleration of the solar rotation while the radial flux of an…
-mode strengthening from a localized bipolar subsurface magnetic field
Nishant K. Singh, Harsha Raichur, Maarit J. Käpylä +3
Recent numerical work in helioseismology has shown that a periodically varying subsurface magnetic field leads to a fanning of the -mode, which emerges from the density jump at…
Bihelical spectrum of solar magnetic helicity and its evolution
Nishant K. Singh, Maarit J. Käpylä, Axel Brandenburg +3
Using a recently developed two-scale formalism to determine the magnetic helicity spectrum (Brandenburg et al. 2017), we analyze synoptic vector magnetograms built with data from t…
