SOLIS: A Modern Facility for Synoptic Solar Observations

On the strength of solar intra-network fields.

The combination of the German Vacuum Tower Telescope and the prototype of ZIMPOL I (Zuerich Imaging Stokes Polarimeter I), a novel, very sensitive imaging polarimeter, has resulted in the first spectra of solar intra-network (IN) fields in circular …

Dependence of the properties of solar magnetic flux tubes on filling factor. II - Results of an inversion approach

The dependence of the properties of solar magnetic elements on the magnetic filling factor is studied using Stokes V spectra of three lines observed near the center of the solar disk. The inversion technique developed by Keller et al. (1990) is …

Structure of solar magnetic fluxtubes from the inversion of Stokes spectra at disk center

The paper presents an inversion procedure that derives the temperature stratification, the turbulent velocity, and the magnetic field strength of the photospheric layers of small-scale magnetic fields from observed Stokes V spectra and the continuum …
