Multiperiodicity, modulations and flip-flops in variable star light curves III. Carrier fit analysis of LQ Hya photometry for 1982-2014
Nigul Olspert, Maarit J. Käpylä, Jaan Pelt +4
We study LQ Hya photometry for 1982-2014 with the carrier fit (CF) -method and compare our results to earlier photometric analysis and recent Doppler imaging maps. We first utilize…
On the cause of solar-like equatorward migration in global convective dynamo simulations
Jörn Warnecke, Petri J. Käpylä, Maarit J. Käpylä +1
We present results from four convectively-driven stellar dynamo simulations in spherical wedge geometry. All of these simulations produce cyclic and migrating mean magnetic fields.…
Magnetically controlled stellar differential rotation near the transition from solar to anti-solar profiles
Bidya Binay Karak, Petri J. Kapyla, Maarit J. Kapyla +3
Late-type stars rotate differentially owing to anisotropic turbulence in their outer convection zones. The rotation is called solar-like (SL) when the equator rotates fastest and a…
Quenching and anisotropy of hydromagnetic turbulent transport
Bidya Binay Karak, Matthias Rheinhardt, Axel Brandenburg +2
Hydromagnetic turbulence affects the evolution of large-scale magnetic fields through mean-field effects like turbulent diffusion and the effect. For stronger fields, these eff…
Confirmation of bistable stellar differential rotation profiles
P. J. Käpylä, M. J. Käpylä, A. Brandenburg
(abridged) Context: Solar-like differential rotation is characterized by a rapidly rotating equator and slower poles. However, theoretical models and numerical simulations can resu…
