"Asymptotic dynamo-wave models of solar magnetic activity"
K.M. Kuzanyan (IZMIRAN)
Abstract:
In the framework of mean-field
hydromagnetic dynamo theory we constructed an asymptotic model of
traveling dynamo waves for the limiting case of strong generation (large
magnetic Reynolds numbers). The 1D and 2D asymptotic WKB-solutions
describe magnetic field generation in solar and stellar convective
envelopes. The models are based on modern knowledge of internal
structure of the Sun and stars and the results are compared with
available observational data on solar and stellar magnetic fields.
In particular, we studied and analysed distribution of signatures of
the alpha-effect
(inhomogeneity of turbulence) revealed from observable magnetic
fields in solar active regions.
