Genetic Algorithm for Inferring Model Parameters for Flux Transport Dynamo Simulation
The Astrophysical JournalThe Sun exhibits an 11 yr cyclic variation, maintained by dynamo action in the solar interior. Mean-field flux transport dynamo models have successfully reproduced most of the features observed in solar cycles, while the model includes many free ...

Percolation and the Solar Dynamo
The Astrophysical Journal Supplement Series, 2007 The origin of magnetic field sources in the Sun’s dynamo is central to this paper. The Babcock-Leighton dynamo was originally envisaged as a shallow dynamo. The source of the Sun’s magnetism is now generally thought to reside near the base of the convection zone and that these fields rise by buoyancy to initiate sunspots.

Slow Solar Wind: Origin in an Independent Small‐Scale Solar Dynamo
Geophysical Research LettersSeparation of the solar wind (SW) into three flow types (coronal mass ejections (CMEs), high speed streams (HSSs), and slow solar wind (SSW)) reveals an inverse relationship between the percentage of time Earth spends in SSW during a year and its ...

Solar Tachocline Confinement by the Nonaxisymmetric Modes of a Dynamo Magnetic Field
The Astrophysical JournalWe recently presented the first 3D numerical simulation of the solar interior for which tachocline confinement was achieved by a dynamo-generated magnetic field. In this follow-up study, we analyze the degree of confinement as the magnetic field strength

, 1999 It is believed that the magnetic field of the Sun is produced by the dynamo process, which involves nonlinear interactions between the solar plasma and the magnetic field. After summarizing the main characteristics of solar magnetic fields, the basic ideas of dynamo theory are presented.

The Dependence of Joy’s Law and Mean Tilt as a Function of Flux Emergence Phase
The Astrophysical JournalData from the Michelson Doppler Imager (MDI) and Helioseismic and Magnetic Imager (HMI) are analyzed from 1996 to 2023 to investigate tilt angles ( γ ) of bipolar magnetic regions and Joy’s law for Solar Cycles 23 and 24 and a portion of Cycle 25.
