The Magnetic Field in the Solar Atmosphere [PDF]
Astronomy and Astrophysics Review, 2014 This publication provides an overview of magnetic fields in the solar atmosphere with the focus lying on the corona. The solar magnetic field couples the solar interior with the visible surface of the Sun and with its atmosphere.

Magnetic Fields in the Solar Convection Zone
Living Reviews in Solar Physics, 2004 Recent studies of the dynamic evolution of magnetic flux tubes in the solar convection zone are reviewed with focus on emerging flux tubes responsible for the formation of solar active regions. The current prevailing picture is that active regions on the

Solar Magnetism in the Polar Regions
Living Reviews in Solar Physics, 2015 This review describes observations of the polar magnetic fields, models for the cyclical formation and decay of these fields, and evidence of their great influence in the solar atmosphere.

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.

The solar magnetic field [PDF]
Reports on Progress in Physics, 2006 The magnetic field of the Sun is the underlying cause of the many diverse phenomena combined under the heading of solar activity. Here we describe the magnetic field as it threads its way from the bottom of the convection zone, where it is built up by the solar dynamo, to the solar surface, where it manifests itself in the form of sunspots and faculae,

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

The Astrophysical Journal, 2023 We analyze the forces that control the dynamic evolution of a flux rope eruption in a three-dimensional radiative magnetohydrodynamic simulation. The confined eruption of the flux rope gives rise to a C8.5 flare. The flux rope rises slowly with an almost

A Statistical Study on Force-Freeness of Solar Magnetic Fields in the Photosphere
, 2012 It is an indisputable fact that solar magnetic fields are force-free in the corona, where force free fields means that current and magnetic fields are parallel and there is no Lorentz force in the fields.
