Photospheric magnetic field and chromospheric emission
We present a statistical analysis of network and internetwork properties in the photosphere and the chromosphere. For the first time we simultaneously observed (a) the four Stokes parameters of the photospheric iron line pair at 630.2 nm and (b) the intensity profile of the Ca H line at 396.8 nm. The vector magnetic field was inferred from the inversion of the iron lines. We aim at an understan...
متن کاملPhotospheric Magnetic Field of the Sun: Two Patterns of the Longitudinal Distribution
Longitudinal distributions of the photospheric magnetic field studied on the basis of National Solar Observatory (Kitt Peak) data (1976 – 2003) displayed two opposite patterns during different parts of the 11-year solar cycle. Heliolongitudinal distributions differed for the ascending phase and the maximum of the solar cycle on the one hand, and for the descending phase and the minimum on the o...

متن کاملThe Effect of the Differential Rotation of Photospheric Magnetic Features on the Synoptic Frame of the Photospheric Magnetic Field
The effect of the advection of magnetic features on synoptic frames has been estimated and it shows that for the time interval ranging from 4 to 14 days the differential rotation of magnetic features accounts for most of the surface transport of photospheric magnetic fields. It is shown that both the 1996.08.27 19:12:30 synoptic frame with the effect of differential rotation included and the fo...
متن کاملStrong horizontal photospheric magnetic field in a surface dynamo simulation
Context. Observations with the Hinode spectro-polarimeter have revealed strong horizontal internetwork magnetic fields in the quiet solar photosphere. Aims. We aim at interpreting the observations by means of results from numerical simulations. Methods. Radiative MHD simulations of dynamo action by near-surface convection are analyzed with respect to the relation between vertical and horizontal...
