Molecular cloud abundances and anomalous diffusion
G. Marschalko, K. Petrovay, E. Forgacs-Dajka
The chemistry of molecular clouds has been studied for decades, with an increasingly general and sophisticated treatment of the reactions involved. Yet the treatment of turbulent d…
Dynamics of the fast solar tachocline: II. Migrating field
E. Forgacs-Dajka
We present detailed numerical calculations of the fast solar tachocline based on the assumption that the dynamo field dominates over the dynamics of the tachocline. In the present…
Long-term variation in distribution of sunspot groups
E. Forgacs-Dajka, B. Major, T. Borkovits
We studied the relation between the distribution of sunspot groups and the Gleissberg cycle. As the magnetic field is related to the area of the sunspot groups, we used area-weight…
Dynamics of the fast solar tachocline: I. Dipolar field
E. Forgacs-Dajka, K. Petrovay
One possible scenario for the origin of the solar tachocline, known as the "fast tachocline", assumes that the turbulent diffusivity exceeds eta>10^9 cm^2/s. In this case the dynam…
The Role of Active Regions in the Generation of Torsional Oscillations
K. Petrovay, E. Forgacs-Dajka
We present a model for torsional oscillations where the inhibiting effect of active region magnetic fields on turbulence locally reduces turbulent viscous torques, leading to a cyc…
Tachocline Confinement by an Oscillatory Magnetic Field
E. Forgacs-Dajka, K. Petrovay
Helioseismic measurements indicate that the solar tachocline is very thin, its full thickness not exceeding 4% of the solar radius. The mechanism that inhibits differential rotatio…
