The evolution of a spot–spot-type solar active region which produced a major solar eruption
Frontiers in Astronomy and Space Sciences, 2023 Solar active regions are the main sources of large solar flares and coronal mass ejections. It is found that the active regions producing large eruptions usually show compact, highly sheared polarity inversion lines.

TANGLED MAGNETIC FIELDS IN SOLAR PROMINENCES [PDF]
The Astrophysical Journal, 2010 Solar prominences are an important tool for studying the structure and evolution of the coronal magnetic field. Here we consider so-called "hedgerow" prominences, which consist of thin vertical threads. We explore the possibility that such prominences are supported by tangled magnetic fields. A variety of different approaches are used.

On the Origin of the Photospheric Magnetic Field
The Astrophysical Journal, 2022 This article presents results that challenge the paradigms that (1) the convection zone is the source of the radial magnetic field in the photosphere and (2) that coronal currents are neutralized from the perspective of the photosphere.

Effects of Partial Ionization on Magnetic Flux Emergence in the Sun
The Astrophysical Journal, 2023 We have performed 3D numerical simulations to investigate the effect of partial ionization on the process of magnetic flux emergence. In our study, we have modified the single-fluid MHD equations to include the presence of neutrals and have performed two

MESOGRANULATION AND THE SOLAR SURFACE MAGNETIC FIELD DISTRIBUTION [PDF]
The Astrophysical Journal, 2011 The relation of the solar surface magnetic field with mesogranular cells is studied using high spatial (~ 100 km) and temporal (~ 30 sec) resolution data obtained with the IMaX instrument aboard SUNRISE. First, mesogranular cells are identified using Lagrange tracers (corks) based on horizontal velocity fields obtained through Local Correlation ...

The Astrophysical Journal, 2023 The solar magnetic structure changes over the solar cycle. It has a dipole structure during solar minimum, where the open flux extends mainly from the polar regions into the interplanetary space.
