Non-LTE Inversion of Spectropolarimetric and Spectroscopic Observations of a Small Active-region Filament Observed at the VTT
Original language description
An active region mini-filament was observed by VTT simultaneously in the He r10 830 angstrom triplet by the TIP 1 spectropolarimeter, in H alpha by the TESOS FabryPerot interferometer, and in Ca n 8542 angstrom by the VTT spectrograph. The spectropolarimetric data were inverted using the HAZEL code and H alpha profiles were modelled solving a NLTE radiative transfer in a simple isobaric and isothermal 2D slab irradiated both from bottom and sides. It was found that the mini-filament is composed of horizontal fluxtubes, along which the cool plasma of T similar to 10 000 K can flow by very large even supersonic - velocities.
