Injection of magnetic helicity in solar cycle 24 and early phase of cycle 25
H. Q. Zhang, S. B. Yang, K. M. Kuzanyan +3
The injection of magnetic helicity into the heliosphere during solar cycle 24 and the early phase of cycle 25 has been calculated based on the analysis of a series of synoptic magn…
Estimates of current helicity and tilt of solar active regions and Joy's law
K. Kuzanyan, N. Kleeorin, I. Rogachevskii +2
The tilt angle, current helicity and twist of solar magnetic fields can be observed in solar active regions. We carried out estimates of these parameters by two ways. Firstly, we c…
The origin and effect of hemispheric helicity imbalance in solar dynamo
S. Yang, V. V. Pipin, D. D. Sokoloff +2
In this paper we study the effects of hemispheric imbalance of magnetic helicity density on breaking the equatorial reflection symmetry of the dynamo generated large-scale magnetic…
The mean tilt of sunspot bipolar regions: theory, simulations and comparison with observations
N. Kleeorin, N. Safiullin, K. Kuzanyan +3
A theory of the mean tilt of sunspot bipolar regions (the angle between a line connecting the leading and following sunspots and the solar equator) is developed. A mechanism of for…
Improvements of the Longitudinal Magnetic Field Measurement from the Solar Magnetic Field Telescope at Huairou Solar Observing Station
Andrei Plotnikov, Alexander Kutsenko, Shanbin Yang +4
The weak-field approximation implying linear relationship between Stokes and longitudinal magnetic field, , often suffers from saturation observed in strong magnet…
Large Scale Properties of Tilt of Sunspot Groups and Joy's Law Near The Solar Equator
K. M. Kuzanyan, N. Safiullin, N. Kleeorin +2
We present a physical mechanism of formation of tilt angles of sunspots due to the process of formation of active regions below the solar photosphere. The contribution of Coriolis…
