Investigating Alfvénic wave propagation in coronal open-field regions. [PDF]
Nat Commun, 2015 The physical mechanisms behind accelerating solar and stellar winds are a long-standing astrophysical mystery, although recent breakthroughs have come from models invoking the turbulent dissipation of Alfvén waves.

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 ...

The Astrophysical Journal, 2023 The lack of observed sausage perturbations in solar active region loops is customarily attributed to the relevance of cutoff axial wavenumbers and the consequent absence of trapped modes (called “evanescent eigenmodes” here).

MAGNETOHYDRODYNAMIC SLOW MODE WITH DRIFTING He++: IMPLICATIONS FOR CORONAL SEISMOLOGY AND THE SOLAR WIND [PDF]
The Astrophysical Journal, 2014 The MHD slow mode wave has application to coronal seismology, MHD turbulence, and the solar wind where it can be produced by parametric instabilities. We consider analytically how a drifting ion species (e.g. He$^{++}$) affects the linear slow mode wave in a mainly electron-proton plasma, with potential consequences for the aforementioned applications.

SEISMOLOGY OF A LARGE SOLAR CORONAL LOOP FROM EUVI/STEREOOBSERVATIONS OF ITS TRANSVERSE OSCILLATION [PDF]
The Astrophysical Journal, 2009 The first analysis of a transverse loop oscillation observed by both Solar TErrestrial RElations Observatories (STEREO) spacecraft is presented, for an event on the 2007 June 27 as seen by the Extreme Ultraviolet Imager (EUVI). The three-dimensional loop geometry is determined using a three-dimensional reconstruction with a semicircular loop model ...

A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region
The Astrophysical Journal, 2023 Coronal loop oscillations are common phenomena in the solar corona, which are often classified as decaying and decayless oscillations. Using the high-resolution observation measured by the Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter, we ...

3D reconstruction of coronal loops by the principal component analysis [PDF]
, 2013 Knowing the three dimensional structure of plasma filaments in the uppermost part of the solar atmosphere, known as coronal loops, and especially their length, is an important parameter in the wave-based diagnostics of this part of the Sun.

MHD simulations of coronal heating [PDF]
, 2015 The problem of heating the solar corona requires the conversion of magnetic energy into thermal energy. Presently, there are two promising mechanisms for heating the solar corona: wave heating and nanoflare heating.
