Alfvénic Perturbations in a Sunspot Chromosphere Linked to Fractionated Plasma in the Corona

چکیده

Abstract In this study, we investigate the spatial distribution of highly varying plasma composition around one largest sunspots solar cycle 24. Observations photosphere, chromosphere, and corona are brought together with magnetic field modeling sunspot in order to probe conditions that regulate degree fractionation within loop populations differing connectivities. We find that, coronal above umbra, has photospheric composition. Coronal loops rooted penumbra contain fractionated plasma, highest levels observed connect active region. Tracing lines from regions locations Alfvénic fluctuations detected chromosphere shows they magnetically linked. These results indicate a connection between chromospheric activity observable changes

Observations of Running Waves in a Sunspot Chromosphere

Spectropolarimetric time series data of the primary spot of active region NOAA 9448 were obtained in the Si i 10827 Å line and the He i 10830 Å multiplet with the Tenerife Infrared Polarimeter. Throughout the time series the spectrograph slit was fixed over a region covering umbra, a light bridge, penumbra, and quiet sun. We present speeds of running penumbral waves in the chromosphere, their r...

Coupling from the photosphere to the chromosphere and the corona

The atmosphere of the Sun is characterized by a complex interplay of competing physical processes: convection, radiation, conduction, and magnetic fields. The most obvious imprint of the solar convection and its overshooting in the low atmosphere is the granulation pattern. Beside this dominating scale there is a more or less smooth distribution of spatial scales, both towards smaller and large...
