SpaceInn local helioseismology
Laurent Gizon (Max Planck Institute for Solar System Research)
The purpose of SpaceInn local helioseismology activities is to maintain an archive of selected data cubes, modeling tools, data analysis tools, and technical information about HMI observations. These are openly available at http://www.mps.mpg.de/projects/seismo/SpaceInn/. Current topics of investigation include meridional circulation, medium- and large-scale convection, magnetic flux emergence, and active region dynamics. Local helioseismology, in combination with realistic numerical simulations of solar magnetoconvection, enables us to construct physics-based models of the interaction of oscillations with convection (essential to understand near-surface effects) and to characterize the seismic signature of sunspots and active regions, two examples that are relevant to global helioseismology and asteroseismology.
