Solar Coronal Magnetic Fields [PDF]
Symposium - International Astronomical Union, 1993 A short compilation of various radio methods of the determination of magnetic fields in the solar corona is given which, completed by observations in other spectral ranges (e.g. the optical and X-ray ranges), results in a complex picture of the magnetic field.

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

The Magnetic Field of Solar Spicules [PDF]
, 2009 Determining the magnetic field of solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in the thermal, dynamic, and magnetic structure of the chromosphere. Here we report on magnetic spicule properties in a very quiet region of the off-limb solar atmosphere, as inferred from new ...

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.

Splitting and Reconstruction of a Solar Filament Caused by Magnetic Emergence and Reconnection
The Astrophysical Journal, 2023 We present observations and interpretation of a nonerupting filament in NOAA active region (AR) 12827 that undergoes splitting and restructuring on 2021 June 4, using the high-resolution data obtained by the New Vacuum Solar Telescope, the Solar Dynamics

Helicity of the solar magnetic field [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractHelicity measures complexity in the field. Magnetic helicity is given by a volume integral over the scalar product of magnetic field B and its vector potential A. A direct computation of magnetic helicity in the solar atmosphere is not possible due to unavailability of the observations at different heights and also due to non-uniqueness of A ...

Association Between Magnetic Pressure Difference and the Movement of Solar Pores
The Astrophysical Journal, 2023 Solar pores are closely related to the concentration, dissipation, and transportation of solar magnetic flux. Their observable characteristics can provide constraints on models and simulations of magnetic flux emergence and formation.

Extreme solar storms based on solar magnetic field [PDF]
Journal of Atmospheric and Solar-Terrestrial Physics, 2018 Many questions have to be answered before understanding the relationship between the emerging magnetic flux through the solar surface and the extreme geoeffective events. Which threshold determines the onset of the eruption? What is the upper limit in energy for a flare? Is the size of sunspot the only criteria to get extreme solar events?
