Learned infinite elements for helioseismology -- Learning transparent boundary conditions for the solar atmosphere
Damien Fournier, Janosch Preuss, Thorsten Hohage +1
Context. Acoustic waves in the Sun are affected by the atmospheric layers, but this region is often ignored in forward models due to the increase in computational cost. Aims. The p…
