The Analysis of Penumbral Fine Structure Using an Advanced Inversion Technique
Original language description
We present a method to study the penumbral fine structure using data obtained by the spectropolarimeter onboard Hinode. For the first time, the penumbral filaments can be considered as resolved in spectropolarimetric measurements. This enables us to useinversion codes with only one-component model atmospheres, and thus assign the obtained stratifications of plasma parameters directly to the penumbral fine structure. This approach is applied to the limb-side part of the penumbra in active region NOAA 10923. The preliminary results show a clear dependence of the plasma parameters on continuum intensity in the inner penumbra, i.e. weaker and horizontal magnetic field along with increased line-of-sight velocity are found in the low layers of the bright filaments.

Analýza jemné struktury penumbry s použitím pokročilé inverzní techniky
Czech description
Je uvedena metoda urcena ke studiu jemne struktury penumbry pri pouziti spektropolarimetrickych dat z Hinode. Poprve jsou rozliseny penumbralni filamenty v pripade mereni spektropolarimetrem. To nam umoznuje pouzivat inverzni kod s pouze jednou slozkou atmosfery a diky tomu urcit rozvrstveni parametru plazmy v jednotlivych filamentech. Tento postup je aplikovan na data pozorovana v penumbre v aktivni oblasti NOAA 10930. Predbezne vysledky ukazuji na zrejmou zavislost mezi parametry plazmy a intenzitou kontinua ve vnitrni penumbre; magneticke pole je slabsi a vice horizontalni a pozorovane rychlosti vyssi v nizkych vrstvach atmosfery v jasnych filamentech.
