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…
The small-scale structure of photospheric convection retrieved by a deconvolution technique applied to Hinode/SP data
T. Oba, T. L. Riethmüller, S. K. Solanki +3
Solar granules are bright patterns surrounded by dark channels called intergranular lanes in the solar photosphere and are a manifestation of overshooting convection. Observational…
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…
The second flight of the SUNRISE balloon-borne solar observatory: overview of instrument updates, the flight, the data and first results
S. K. Solanki, T. L. Riethmüller, P. Barthol +32
The SUNRISE balloon-borne solar observatory, consisting of a 1~m aperture telescope that provided a stabilized image to a UV filter imager and an imaging vector polarimeter, carrie…
Brightness of Solar Magnetic Elements as a Function of Magnetic Flux at High Spatial Resolution
F. Kahil, T. L. Riethmüller, S. K. Solanki
We investigate the relationship between the photospheric magnetic field of small-scale magnetic elements in the quiet Sun (QS) at disc centre, and the brightness at 214 nm, 300 nm,…
