We rely on the following two codes for the propagation of waves in the Sun:
-
the software hawen for the propagation of waves in the Sun: see the dedicated website: https://ffaucher.gitlab.io/hawen-website/
-
the software Montjoie (https://www.math.u-bordeaux.fr/~durufle/codes.php), you can download the movie of solar wave propagation.
