Standing Kink Waves in Sigmoid Solar Coronal Loops: Implications for Coronal Seismology [PDF]
Astrophysical Journal Letters, 2020 Abstract Using full three-dimensional magnetohydrodynamic numerical simulations, we study the effects of magnetic field sigmoidity or helicity on the properties of the fundamental kink oscillation of solar coronal loops. Our model consists of a single denser coronal loop, embedded in a plasma with dipolar force-free magnetic field with a

Diagnostics of the Solar Coronal Plasmas by Magnetohydrodynamic Waves: Magnetohydrodynamic Seismology [PDF]
Reviews of Modern Plasma PhysicsAbstractMacroscopic wave and oscillatory phenomena ubiquitously detected in the plasma of the corona of the Sun are interpreted in terms of magnetohydrodynamic theory. Fast and slow magnetoacoustic waves are clearly distinguished in observations. Properties of coronal magnetohydrodynamic waves are determined by local parameters of the plasma, including

Coronal seismology by slow waves in non-adiabatic conditions
Frontiers in Astronomy and Space Sciences, 2022 Slow magnetoacoustic waves represent an important tool for probing the solar coronal plasma. The majority of seismological methods with slow waves are based on a weakly non-adiabatic approach, which assumes the coronal energy transport has only weak ...

Seismological constraints on the solar coronal heating function [PDF]
Astronomy & Astrophysics, 2020 Aims. The hot solar corona exists because of the balance between radiative and conductive cooling and some counteracting heating mechanism that remains one of the major puzzles in solar physics. Methods. The coronal thermal equilibrium is perturbed by magnetoacoustic waves, which are abundantly present in the corona, causing a misbalance between the ...
