Universal dynamo paradigm for solar activity, Higgs fields and disasters [PDF]
EPJ Web of Conferences, 2021 There is still a problem of a correct and accurate description of the dynamo and its uses in various fields of physics. To solve this problem, a special and universal representation of dynamo is proposed.

The 8‐Year Solar Cycle During the Maunder Minimum
AGU Advances, 2023 The presence of grand minima, characterized by significantly reduced solar and stellar activity, brings a challenge to the understanding of solar and stellar dynamo. The Maunder Minimum (1645–1715 AD) is a representative grand solar minimum.

Nonlinearity, time delay, and Grand Maxima in supercritical Babcock-Leighton dynamos
Journal of Space Weather and Space Climate, 2023 The physical origin of centennial and millennial-scale variations in solar activity remains ill-understood. Although stochastic fluctuations of the solar dynamo are unavoidable in view of the turbulent nature of the solar convection zone, the ...

Theoretical study of the ionospheric dynamo region inside the South Atlantic Anomaly
Earth and Planetary Physics, 2023 The South Atlantic Anomaly (SAA) is a region where the geomagnetic field is significantly lower than that of the surrounding area. On the basis of the models of CHAOS-7.8, Mass Spectrometer Incoherent Scatter Model (NRLMSISE-00), and International ...

The role of the bow shock in solar wind-magnetosphere coupling [PDF]
Annales Geophysicae, 2011 In this paper we examine the role of the bow shock in coupling solar wind energy to the magnetosphere using global magnetohydrodynamic simulations of the solar wind-magnetosphere interaction with southward IMF.

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 The origins of solar magnetism lie below the visible surface of the Sun, in the highly turbulent convection zone. Turbulent convection operates in conjunction with rotational shear, global circulations and intricate boundary layers to produce the rich diversity of magnetic activity we observe.
