Magnetohydrodynamic Waves in Multi-Layered Asymmetric Waveguides: Solar Magneto-Seismology Theory and Application

Frontiers in Astronomy and Space Sciences, 2019
Diagnosing the solar atmospheric plasma is one of the major challenges in solar physics. Magnetohydrodynamic (MHD) waves, by means of applying the powerful concept of solar magneto-seismology (SMS), provide a tool to obtain diagnostic insight into the ...

Interrogating solar flare loop models with IRIS observations 1: Overview of the models, and mass flows

Frontiers in Astronomy and Space Sciences, 2022
Solar flares are transient yet dramatic events in the atmosphere of the Sun, during which a vast amount of magnetic energy is liberated. This energy is subsequently transported through the solar atmosphere or into the heliosphere, and together with ...

Three-dimensional numerical simulation of magnetohydrodynamic-gravity waves and vortices in the solar atmosphere [PDF]

, 2013
With the adaptation of the FLASH code we simulate magnetohydrodynamic-gravity waves and vortices as well as their response in the magnetized three-dimensional (3D) solar atmosphere at different heights to understand the localized energy transport ...

Resonant Damping of Propagating Kink Waves in Non-stationary, Longitudinally Stratified, and Expanding Solar Waveguides

Frontiers in Astronomy and Space Sciences, 2019
Propagating kink waves have been observed in many magnetic waveguides in the solar atmosphere, like coronal magnetic loops, spicules, and fine structures of prominences. There are also observational evidences that these waves are damped.

Interrogating solar flare loop models with IRIS observations 2: Plasma properties, energy transport, and future directions

Frontiers in Astronomy and Space Sciences, 2023
During solar flares a tremendous amount of magnetic energy is released and transported through the Sun’s atmosphere and out into the heliosphere. Despite over a century of study, many unresolved questions surrounding solar flares are still present. Among

Analytical Solution of the Hanle Effect in View of CLASP and Future Polarimetric Solar Studies

Atoms, 2019
We have solved a problem of the Hanle effect for the hydrogen Lyman- α line in an intuitive and straightforward way. The Stokes parameters amid an anisotropic radiation field and a magnetic field are derived as an analytical formula which ...

Evaluation of High Resolution WRF Solar

Energies, 2023
The amount of solar irradiation that reaches Earth’s surface is a key quantity of solar energy research and is difficult to predict, because it is directly affected by the changing constituents of the atmosphere.
