Evershed and counter-Evershed flows in sunspot MHD simulations
A. L. Siu-Tapia, M. Rempel, A. Lagg +1
There have been a few reports in the literature of counter-Evershed flows observed in well developed sunspot penumbrae, i.e. flows directed towards the umbra along penumbral filame…
Normal and counter Evershed flows in the photospheric penumbra of a sunspot. SPINOR 2D inversions of Hinode-SOT/ SP observations
A. Siu-Tapia, A. Lagg, S. K. Solanki +2
Context. The Evershed effect, a nearly horizontal outflow of material seen in the penumbrae of sunspots in the photospheric layers, is a common characteristic of well-developed pen…
Three-dimensional magnetic structure of a sunspot: comparison of the photosphere and upper chromosphere
Jayant Joshi, Andreas Lagg, Johann Hirzberger +1
We investigate the magnetic field of a sunspot in the upper chromosphere and compare it to the field's photospheric properties. We observed the main leading sunspot of the active r…
Extended subadiabatic layer in simulations of overshooting convection
Petri J. Käpylä, Matthias Rheinhardt, Axel Brandenburg +5
We present numerical simulations of hydrodynamic overshooting convection in local Cartesian domains. We find that a substantial fraction of the lower part of the convection zone (C…
Oscillations on width and intensity of slender Ca II H fibrils from Sunrise/SuFI
R. Gafeira, S. Jafarzadeh, S. K. Solanki +12
We report the detection of oscillations in slender Ca II H fibrils (SCFs) from high-resolution observations acquired with the Sunrise balloon-borne solar observatory. The SCFs show…
Flows along arch filaments observed in the GRIS 'very fast spectroscopic mode'
S. J. González Manrique, C. Denker, C. Kuckein +28
A new generation of solar instruments provides improved spectral, spatial, and temporal resolution, thus facilitating a better understanding of dynamic processes on the Sun. High-r…
