Meridional circulation and dynamo waves

H Popova, D Sokoloff - … Nachrichten: Astronomical Notes, 2008 - Wiley Online Library
The effect of meridional circulation on spherical shell dynamos is considered in the Parker
approximation. We demonstrate that the type of the exited solution crucially depend on the …

The quasi-biennial cycle of solar activity and dynamo theory

EP Popova, NA Yukhina - Astronomy Letters, 2013 - Springer
We have investigated the behavior of dynamo waves within the framework of a nonlinear αω-
dynamo by taking into account the thickness of the convective zone, turbulent diffusivity, and …

Current results on the asymptotics of dynamo models

HP Popova - Physics-Uspekhi, 2016 - iopscience.iop.org
Magnetic field generation and evolution models that are capable of describing a large body
of observational material are currently available for different celestial bodies. Despite recent …

Double cycle of solar activity in a two-layer medium

EP Popova, KA Potemina, NA Yukhina - Geomagnetism and Aeronomy, 2014 - Springer
It is commonly accepted that the magnetic field of the Sun and other stars is generated
through the operation of the dynamo mechanism which is based on taking into account the …

Modeling of the solar activity double cycle using dynamical systems

EP Popova, KA Potemina - Geomagnetism and Aeronomy, 2013 - Springer
The generation and evolution of the Sun's magnetic field and other stars is usually related to
the dynamo mechanism. This mechanism is based on the consideration of the joint influence …

Dynamical systems for modeling the evolution of the magnetic field of stars and Earth

H Popova - Journal of Physics: Conference Series, 2016 - iopscience.iop.org
The cycles of solar magnetic activity are connected with a solar dynamo that operates in the
convective zone. Solar dynamo mechanism is based on the combined action of the …

An asymptotic solution of a kinematic-dynamo with meridional circulation

AM Soward, AP Bassom, KM Kuzanyan… - … & Astrophysical Fluid …, 2013 - Taylor & Francis
Asymptotic methods are used to study a one-dimensional kinematic-Parker dynamo wave
model in the limit when the strength of the-sources, as measured by the dynamo number, is …

A low-mode dynamo with meridional circulation and dipolar symmetry of the magnetic field

EP Popova - Astronomy reports, 2012 - Springer
A dynamic system for the Parker dynamo including meridional circulation that is applicable
to astrophysical objects is constructed. The meridional circulation is able to control the …
