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 ...

Polarisation of decayless kink oscillations of solar coronal loops [PDF]
Nature Communications, 2023 Decayless kink oscillations of plasma loops in the solar corona may contain an answer to the enigmatic problem of solar and stellar coronal heating. The polarisation of the oscillations gives us a unique information about their excitation mechanisms and ...

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 ...

ALFVÉN WAVE SOLAR MODEL (AWSoM): CORONAL HEATING [PDF]
The Astrophysical Journal, 2014 We present a new version of the Alfven Wave Solar Model (AWSoM), a global model from the upper chromosphere to the corona and the heliosphere. The coronal heating and solar wind acceleration are addressed with low-frequency Alfven wave turbulence. The injection of Alfven wave energy at the inner boundary is such that the Poynting flux is proportional ...

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 ...

Estimating Ion Temperatures at the Polar Coronal Hole Boundary
The Astrophysical Journal, 2023 The temperatures of the heavy ions ( T _i ) in the solar corona provide critical information about the heating mechanism of the million-degree corona.
