The radial gradient of the near-surface shear layer of the Sun
Atefeh Barekat, Jesper Schou, Laurent Gizon
Helioseismology has provided unprecedented information about the internal rotation of the Sun. One of the important achievements was the discovery of two radial shear layers: one n…
Image compression in local helioseismology
Björn Löptien, Aaron C. Birch, Laurent Gizon +1
Context. Several upcoming helioseismology space missions are very limited in telemetry and will have to perform extensive data compression. This requires the development of new met…
Magnetic Flux Transport at the Solar Surface
J. Jiang, D. H. Hathaway, R. H. Cameron +3
After emerging to the solar surface, the Sun's magnetic field displays a complex and intricate evolution. The evolution of the surface field is important for several reasons. One i…
Time-distance helioseismology: A new averaging scheme for measuring flow vorticity
Jan Langfellner, Laurent Gizon, Aaron C. Birch
Time-distance helioseismology provides information about vector flows in the near-surface layers of the Sun by measuring wave travel times between points on the solar surface. Spec…
Helioseismology with Solar Orbiter
Björn Löptien, Aaron C. Birch, Laurent Gizon +10
The Solar Orbiter mission, to be launched in July 2017, will carry a suite of remote sensing and in-situ instruments, including the Polarimetric and Helioseismic Imager (PHI). PHI…
Generalization of the noise model for time-distance helioseismology
Damien Fournier, Laurent Gizon, Thorsten Hohage +1
In time-distance helioseismology, information about the solar interior is encoded in measurements of travel times between pairs of points on the solar surface. Travel times are ded…
