Magnetic Fields in the Solar Convection Zone

Living Reviews in Solar Physics, 2009
Active regions on the solar surface are generally thought to originate from a strong toroidal magnetic field generated by a deep seated solar dynamo mechanism operating at the base of the solar convection zone.

Magnetic Flux Emergence and Solar Eruptions in Partially Ionized Plasmas

The Astrophysical Journal
We have performed 3D MHD simulations to study the effect of partial ionization in the process of magnetic flux emergence in the Sun. In fact, we continue previous work, and we now focus (1) on the emergence of the magnetic fields above the solar ...

Formation of a Magnetic Flux Rope prior to the Eruption: Insight from a Radiative MHD Simulation of Active Region Emergence

The Astrophysical Journal Letters
Magnetic flux ropes are fundamental magnetic structures in solar eruptions, whose formation is generally attributed to: (1) the emergence of subsurface flux tubes; or (2) flux cancellation driven by photospheric horizontal flows and magnetic reconnection.

Differential Rotation of the Solar Chromosphere: A Century-long Perspective from Kodaikanal Solar Observatory Ca ii K Data

The Astrophysical Journal
Chromospheric differential rotation is a key component in comprehending the atmospheric coupling between the chromosphere and the photosphere at different phases of the solar cycle. In this study, we therefore utilize the newly calibrated multidecadal Ca

Filamentary Structures Formation around a Magnetic Pore Using High-resolution Observations of the Goode Solar Telescope

The Astrophysical Journal
With the aid of high-resolution spatial and temporal observations from the Goode Solar Telescope, we present an investigation of the emergence, coalescence, and submergence of a moving magnetic feature (MMF) in the region surrounding a magnetic pore ...
