The magnetic fields, activity and hidden companions of solar-type stars [PDF]
, 2023 The magnetic fields of the Sun and other solar-type stars manifest in a range of observable surface phenomena that provide insight into the magnetic dynamos operating within, but also hamper the detection of exoplanets.

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.

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.

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

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
