Solar magnetic fields as revealed by Stokes polarimetry
Stenflo, J. O.
Observational astrophysics started when spectroscopy could be applied to astronomy. Similarly, observational work on stellar magnetic fields became possible with the application of spectro-polarimetry. In recent decades there have been dramatic advances in the observational tools for spectro-polarimetry. The four Stokes parameters that provide a c…
Solar flares at submillimeter wavelengths
Krucker, Säm; Kretzschmar, M.; Klein, K. -L. +10 more
We discuss the implications of the first systematic observations of solar flares at submillimeter wavelengths, defined here as observing wavelengths shorter than 3 mm (frequencies higher than 0.1 THz). The events observed thus far show that this wave band requires a new understanding of high-energy processes in solar flares. Several events, includ…
