Magneto-acoustic wave propagation in the solar atmosphere: vertical magnetic field, disturbance $\delta B$

Co-Authors: M. Roth, O. Steiner
Magnetic field perturbations, $\delta B/B_0$, for different time steps and for the scenario of a vertical magnetic field. The magneto-acoustic wave propagates from the source (piston) located at (x; z) = (1000; -750) km. The ho ...

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

Co-Authors: M. Roth, O. Steiner
The 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 $c_\mathrm{s} =c_\mathrm{A}$.
