Convective blueshifts in the solar atmosphere, I. Absolute measurements with LARS of the spectral lines at 6302 Å
Johannes Löhner-Böttcher, Wolfgang Schmidt, Franziska Stief +2
The solar convection manifests as granulation and intergranulation at the solar surface. In the photosphere, convective motions induce differential Doppler shifts to spectral lines…
Maximum Entropy Limit of Small-scale Magnetic Field Fluctuations in the Quiet Sun
A. Y. Gorobets, S. V. Berdyugina, T. L. Riethmüller +12
The observed magnetic field on the solar surface is characterized by a very complex spatial and temporal behavior. Although feature-tracking algorithms have allowed us to deepen ou…
LARS - An Absolute Reference Spectrograph for solar observations, Upgrade from a prototype to a turn-key system
J. Loehner-Boettcher, W. Schmidt, H. -P. Doerr +4
LARS is an Absolute Reference Spectrograph designed for ultra-precise solar observations. The high-resolution echelle spectrograph of the Vacuum Tower Telescope is supported by a s…
Magneto-static modelling from SUNRISE/IMaX: Application to an active region observed with SUNRISE II
T. Wiegelmann, T. Neukirch, D. H. Nickeler +13
Magneto-static models may overcome some of the issues facing force-free magnetic field extrapolations. So far they have seen limited use and have faced problems when applied to qui…
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…
