Magneto-acoustic wave propagation in a magnetic flux sheet (strong field)
Author: Vigeesh GangadharanTemperature perturbations in a magnetic flux sheet (strong field) due to waves excited by a horizontal motion at the bottom boundary. The excitation generates fast magneto-acoustic wave (predominantly magnetic) along with slow mag ... more Views: 605
Running umbral/penumbral waves - The GREGOR Fabry-Perot Interferometer @ the 1.5m GREGOR Solar Telescope - First Halpha Spectra from 7 October 2013
Author: Klaus Gerhard PuschmannHalpha Time series recorded with the GREGOR Fabry-Perot Interferometer @ the 1.5m GREGOR Solar Telescope on 7 October 2013. Left to right/top to bottom: Velocity @ 90% & 17% Line Depression (LD); Bisector Width @ 17%, 33%, 50% & ... more Views: 997
Magneto-acoustic wave propagation in a magnetic flux sheet (moderate field)
Author: Vigeesh GangadharanTemperature perturbations in a magnetic flux sheet (moderate field strength) due to waves excited by a horizontal motion at the bottom boundary. The waves higher up are predominantly acoustic (slow magneto-acoustic) that propagat ... more Views: 391

Magneto-acoustic wave propagation in the solar atmosphere: tilted magnetic field ($\theta=-30^°$)
Author: Christian NuttoEvolution of the velocity perturbation scaled with the square root of the density, $\rho^{1/2}\delta |v|$, for the scenario of a tilted magnetic field with $\theta= -30^°$. The horizontal line shows the equipartition level, w ... more Views: 570
Simulation of a spherical magneto-acoustic wave propagating in the solar atmosphere: interaction with magnetic canopy, $\delta v$
Author: Christian NuttoThe spherical magneto-acoustic wave is excited right beneath the magnetic canopy. The color map shows the velocity perturbations $\delta |v|$. The green contours display the equipartition level, where $c_\mathrm{s} =c_\mathrm{A}$. Views: 681
