Description
  • An analysis of Stokes observations of a penumbra in active region NOAA 8990 is presented. The observations were recorded with the La Palma Stokes Polarimeter attached to the 1-m Swedish Solar Telescope. The stratification in the solar atmosphere of different physical parameters is retrieved from these data using the Stokes Inversion based on Response functions (SIR). Our results confirm previous findings, that with increasing distance from the umbra the magnetic field becomes weaker and more horizontal and the line-of-sight velocities increase. The results suggest the existence of unresolved filamentary structure in the spatial distributions of temperature, magnetic field strength and inclination. The maps of temperature and magnetic field strength along the vertical cuts through the penumbra indicate the presence of rising flux tubes, predicted theoretically by Schlichenmaier (1998).

  • Prezentujeme analýzu pozorování Stokesových profilů v penumbře v aktivní oblasti NOAA 8990. Data byla získána s pomocí La Palma Stokes Polarimetru na Švédském vakuovém slunečním teleskopu. Zvrstvení parametrů palsmy ve sluneční atmosféře bylo získáno za pomocí inerzního kódu SIR. Výsledky potvrzují dříve zjištěná fakta, tedy že magnetické pole slábne a stává se více horizontálním se vzrůstající vzdáleností od umbry, přičemž rychlost plasmy roste. Výsledky prostorového rozdělení teploty a síly a sklonu magnetického pole poukazují na existenci nerozlišené jemné struktury. Mapy teploty a síly magnetického pole podél vertikálních řezů skrz penumbru naznačují přítomnost stoupajících proudových trubic, které byly teoreticky předpovězeny v práci Schlichenmaiera (1998).
