Intermittency spectra of current helicity in solar active regions
A. S. Kutsenko, V. I. Abramenko, K. M. Kuzanyan +2
We analyse the spatial distribution of current helicity in solar active regions. A comparison of current helicity maps derived from three different instruments (Helioseismic and Ma…
The origin of the helicity hemispheric sign rule reversals in the mean-field solar-type dynamo
V. V. Pipin, H. Zhang, D. D. Sokoloff +2
Observations of proxies of the magnetic helicity in the Sun over the past two solar cycles revealed reversals of the helicity hemispheric sign rule (negative in the North and posit…
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…
New dynamo pattern revealed by solar helical magnetic fields
Hongqi Zhang, T. Sakurai, A. Pevtsov +4
Previously unobservable mirror asymmetry of the solar magnetic field -- a key ingredient of the dynamo mechanism which is believed to drive the 11-year activity cycle -- has now be…
