51. Magnetic Field Reconstruction Based on Sunspot Oscillations

Contributed by Johannes Löhner-Böttcher. Posted on April 25, 2016

We observed magnetoacoustic waves propagating along the magnetic field lines of a sunspot. Based on the wave periods and atmospheric characteristics, we reconstructed the magnetic field topology of the sunspot.

46. Spatially Resolved Coronal Magnetic Fields Derived Using Seismology Techniques Applied to Omnipresent Sunspot Waves

Omnipresent magneto-acoustic waves, originating from within the underlying sunspot and propagating radially outwards, allow the spatial variation of the local coronal magnetic field to be mapped with high precision.
