Do Planets Affect the Behavior of the Long-term Solar Activity?
M. M. Katsova, V. N. Obridko, D. D. Sokoloff +1
Solar activity is a process driven by many independent but interconnected phenomena. Although the 11-year cycle is the result of operation of the dynamo mechanism, the cause of lon…
Resonances and Stellar Cycles: Observations and Modelling
M. M. Katsova, F. A. Azizov, V. N. Obridko +2
In the paper we discuss the possibility of the influence of parametric excitation, in particular, planetary gravitational interaction, on the behavior of stellar magnetic activity…
North-South Asymmetry of the Solar Activity at Different Spatial Scales
V. N. Obridko, A. S. Shibalova, D. D. Sokoloff +1
Solar activity seems quite understandable when considered on the scales comparable with a solar cycle, i.e. about 11 years, and on a short time scale of about a year. A solar cycle…
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…
Structures of various types of symmetry in the solar activity cycle
V. N. Obridko, A. S. Shibalova, D. D. Sokoloff
The solar cycle is a complex phenomenon. To comprehensively understand it, we have to study various tracers. The most important component of this complex is the solar dynamo, which…
