Frontiers in Physics, 2021 In the solar coronal numerical simulation, the coronal heating/acceleration and the magnetic divergence cleaning techniques are very important. The coronal–interplanetary total variation diminishing (COIN-TVD) magnetohydrodynamic (MHD) model is developed

The Astrophysical Journal Letters, 2023 We propose that coronal heating in EUV coronal plumes is weaker, not stronger, than in adjacent nonplume coronal magnetic funnels. This expectation stems from (i) the observation that an EUV plume is born as the magnetic flux at the foot of the plume’s ...

Deciphering Solar Coronal Heating: Energizing Small-scale Loops through Surface Convection
The Astrophysical Journal Letters, 2023 The solar atmosphere is filled with clusters of hot small-scale loops commonly known as coronal bright points (CBPs). These ubiquitous structures stand out in the Sun by their strong X-ray and/or extreme-ultraviolet (EUV) emission for hours to days ...

Coronal Heating Rate in the Slow Solar Wind
The Astrophysical Journal Letters, 2023 This Letter reports the first observational estimate of the heating rate in the slowly expanding solar corona. The analysis exploits the simultaneous remote and local observations of the same coronal plasma volume, with the Solar Orbiter/Metis and the ...

The Role of High-frequency Transverse Oscillations in Coronal Heating
The Astrophysical Journal Letters, 2023 Transverse oscillations that do not show significant damping in solar coronal loops are found to be ubiquitous. Recently, the discovery of high-frequency transverse oscillations in small-scale loops has been accelerated by the Extreme Ultraviolet Imager ...

Research progress in coronal magnetic field measurements
地球与行星物理论评, 2022 Different solar atmospheric layers are connected by the magnetic field of the Sun, which is the primary source for various types of solar activity. The magnetic activity of the Sun has a significant impact on the solar-terrestrial environment and human ...
