Magneto-acoustic waves in magnetic flux tube

Author: Vigeesh Gangadharan
Temperature perturbations associated with the propagation of magneto-acoustic waves in a magnetic flux tube. Two scenarios of wave excitation, viz. granular buffeting and swirly motion are studied. Buffeting by granule are likely ... more

Simulation of a spherical magneto-acoustic wave propagating in the solar atmosphere: interaction with magnetic canopy, $\delta B$

Author: Christian Nutto
The spherical magneto-acoustic wave is excited right beneath the magnetic canopy. The color map shows the magnetic field perturbations $\delta B$. The fast magnetic mode in the low regime is supported by magnetic forces, causin ... more
