Current helicity constraints in solar dynamo models
D. Sokoloff, H. Zhang, D. Moss +5
We investigate to what extent the current helicity distribution observed in solar active regions is compatible with solar dynamo models. We use an advanced 2D mean-field dynamo mod…
Waldmeier relations and the solar cycle dynamics by the mean-field dynamos
V. V. Pipin, D. D. Sokoloff, I. G. Usoskin
The long-term variability of the sunspot cycle, as recorded by the Wolf numbers, are imprinted in different kinds of statistical relations which relate the cycle amplitudes, durati…
Helicity conservation in nonlinear mean-field solar dynamo
V. V. Pipin, D. D. Sokoloff, H. Zhang +1
We explore the impact of magnetic helicity conservation on the mean-field solar dynamo using the axisymmetric dynamo model which includes the subsurface shear. Our results support…
Resonances for activity waves in spherical mean field dynamos
David Moss, Dmitri Sokoloff
We study activity waves of the kind that determine cyclic magnetic activity of various stars, including the Sun, as a more general physical rather than a purely astronomical proble…
Ram pressure effects in the galactic plane and galactic dynamos in the no-z approximation
D. Moss, D. Sokoloff, R. Beck
The magnetic field of galaxies is believed to be produced by internal dynamo action, but can be affected by motion of the galaxy through the surrounding medium. Observations of pol…
Lepton asymmetries and primordial hypermagnetic helicity evolution
V. B. Semikoz, D. Sokoloff, J. W. F. Valle
The hypermagnetic helicity density at the electroweak phase transition (EWPT) exceeds many orders of magnitude the galactic magnetic helicity density. Together with previous magnet…
