Alfven Wave Transmission and Heating of Solar Coronal Loops
The Astrophysical Journal, 1998 We discuss the problem of wave transmission from the solar photosphere into coronal loops. We conclude that wave energy can be efficiently transmitted into loops with a sufficiently twisted magnetic field. The value of the required twist is below but close to the threshold for kink instability.

Study on the Responses in the Transition Region of Coronal Extreme-ultraviolet Waves
The Astrophysical JournalCoronal extreme-ultraviolet (EUV) waves are globally propagating disturbances in the solar atmosphere. The existence of coronal EUV waves was predicted by chromospheric Moreton–Ramsey waves.

Damping and Dispersion of Acoustic Waves in the Solar Corona
The Astrophysical JournalWe study one of the most common phenomena in the solar corona—compression waves observed in the extreme ultraviolet range. They are observed throughout various coronal structures, coronal loops and holes.

Measuring the Coronal Magnetic Field with 2D Coronal Seismology: A Forward-modeling Validation
The Astrophysical Journal Supplement SeriesIn recent years, a two-dimensional (2D) coronal seismology technique applied to spectral-imaging data from the Coronal Multi-channel Polarimeter (CoMP) and Upgraded Coronal Multi-channel Polarimeter (UCoMP) has enabled routine measurement of the global ...

Propagating Kink Waves in Chromospheric Jetlike Structures and Coronal Plumelets
The Astrophysical JournalCoronal plumes and chromospheric jetlike structures are believed to be highly dynamic. We report the first direct observations of a propagating kink wave in a chromospheric jetlike structure and its associated plumelet structure in the upper corona of ...

Nonlinearly Wave-Wave Interaction Leads to Solar Coronal Heating
Journal of Condensed MatterNonlinear formulation of slow Alfvén wave in magnetized plasma which can be an essential ingredient of the solar space plasma is being studied. Various method has been adopted, mathematical formulation of the magnetohydrodynamic (MHD) waves can interpret the astrophysical phenomena happening in space plasma.
