Inferring solar differential rotation and viscosity via passive imaging with inertial waves
Tram Thi Ngoc Nguyen, Thorsten Hohage, Damien Fournier +1
The recent discovery of inertial waves on the surface of the Sun offers new possibilities to learn about the solar interior. These waves are long-lived with a period on the order o…
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…
Assembling algorithm for Green's tensors and absorbing boundary conditions for Galbrun's equation in radial symmetry
Ha Pham, Florian Faucher, Damien Fournier +2
Solar oscillations can be modeled by Galbrun's equation which describes Lagrangian wave displacement in a self-gravitating stratified medium. For spherically symmetric backgrounds,…
Quantitative passive imaging by iterative holography: The example of helioseismic holography
Björn Müller, Thorsten Hohage, Damien Fournier +1
In passive imaging, one attempts to reconstruct some coefficients in a wave equation from correlations of observed randomly excited solutions to this wave equation. Many methods pr…
A Babcock-Leighton dynamo model of the Sun incorporating toroidal flux loss and the helioseismically-inferred meridional flow
S. Cloutier, R. H. Cameron, L. Gizon
We investigate whether the Babcock-Leighton flux-transport dynamo model remains in agreement with observations if the meridional flow profile is taken from helioseismic inversions.…
Detecting active latitudes of Sun-like stars using asteroseismic a-coefficients
Othman Benomar, Masao Takata, Michael Bazot +3
We introduce a framework to measure the asphericity of Sun-like stars using , and coefficients, and constrain their latitudes of magnetic activity. Systematic erro…
