Magnetic Field Reconstruction in a Solar Active Region [PDF]
Symposium - International Astronomical Union, 2001 Supposing coronal magnetic fields are in a force-free state from the chromosphere to the height of two solar radii, we reconstruct 3D force-free magnetic fields by making use of a new numerical technique, in which the fields are represented by a boundary integral equation based on a specific Green's function.

Light Bridge and Magnetic Field in a Solar Active Region
The Astrophysical Journal, 2022 Abstract Observational data from the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory and the multiwavelength simultaneous imaging system attached to the New Vacuum Solar Telescope located at Fuxian Lake, China are employed for the study of light bridges and magnetic fields in the active region NOAA 12529. Coronal

On the topology of global coronal magnetic fields [PDF]
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Magnetic Fields of Solar Active Regions [PDF]
Proceedings of the International Astronomical Union, 2004 After briefly summarizing the outstanding achievements and new tendencies witnessed in recent years in the studies of magnetic fields of solar active regions (ARs), we focus on the current understanding on flux appearance and disappearance. On flux appearance, the moving magnetic features (MMFs) stand still as a mystery in solar physics, although the ...

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.

Expulsion of Counter Evershed Flows from Sunspot Penumbrae
The Astrophysical Journal, 2023 In addition to the Evershed flow directed from the umbra toward the outer boundary of a sunspot, under special circumstances a counter Evershed flow (CEF) in the opposite direction also occurs.

Rapid Decay of a Penumbral Sector Associated with a Strong Light Bridge in Active Region NOAA 12680
The Astrophysical Journal, 2023 We present observations of the rapid decay of a penumbral sector associated with a strong light bridge (LB) in the active region NOAA 12680 by analyzing the scattered light-corrected Solar Dynamics Observatory/Helioseismic and Magnetic Imager data.

Chromospheric Magnetic Field of Solar Active Regions
The Astrophysical Journal, 2001 The three-dimensional magnetic field structure of 137 solar active regions is studied by comparing the observed and computed chromospheric magnetograms. The model chromospheric field is obtained by extrapolating the observed photospheric field into the chromosphere with a potential (current-free) magnetic-field model in Cartesian geometry.
