A flux tube solar dynamo model based on the competing role of buoyancy and downflows
L. H. Li, S. Sofia, G. Belvedere
A magnetic flux tube may be considered both as a separate body and as a confined field. As a field, it is affected both by differential rotation (-effect) and cyclonic convectio…
Origin of long-period Alfv{é}n waves in the solar wind
T. V. Zaqarashvili, G. Belvedere
We suggest that the observed long-period Alfv{é}n waves in the solar wind may be generated in the solar interior due to the pulsation of the Sun in the fundamental radial mode. The…
Protoneutron star dynamos and pulsar magnetism
A. Bonanno, V. Urpin, G. Belvedere
We have investigated the turbulent mean-field dynamo action in protoneutron stars that are subject to convective and neutron finger instabilities during the early evolutionary phas…
On a mechanism for enhancing magnetic activity in tidally interacting binaries
T. Zaqarashvili, G. Javakhishvili, G. Belvedere
We suggest a mechanism for enhancing magnetic activity in tidally interacting binaries. We suppose that the deviation of the primary star from spherical symmetry due to the tidal i…
