Bright points in the quiet Sun as observed in the visible and near-UV by the balloon-borne observatory Sunrise
T. L. Riethmueller, S. K. Solanki, V. Martínez Pillet +13
Bright points (BPs) are manifestations of small magnetic elements in the solar photosphere. Their brightness contrast not only gives insight into the thermal state of the photosphe…
Fully resolved quiet-Sun magnetic flux tube observed with the Sunrise IMaX instrument
A. Lagg, S. K. Solanki, T. L. Riethmueller +14
Until today, the small size of magnetic elements in quiet Sun areas has required the application of indirect methods, such as the line-ratio technique or multi-component inversions…
Quiet-Sun intensity contrasts in the near ultraviolet
Johann Hirzberger, Alex Feller, Tino L. Riethmüller +14
We present high-resolution images of the Sun in the near ultraviolet spectral range between 214 nm and 397 nm as obtained from the first science flight of the 1-m Sunrise balloon-b…
Sunrise: instrument, mission, data and first results
S. K. Solanki, P. Barthol, S. Danilovic +16
The Sunrise balloon-borne solar observatory consists of a 1m aperture Gregory telescope, a UV filter imager, an imaging vector polarimeter, an image stabilization system and furthe…
Transverse component of the magnetic field in the solar photosphere observed by Sunrise
S. Danilovic, B. Beeck, A. Pietarila +12
We present the first observations of the transverse component of photospheric magnetic field acquired by the imaging magnetograph Sunrise/IMaX. Using an automated detection method,…
The solar magnetic field
Sami K. Solanki, Bernd Inhester, Manfred Schüssler
The magnetic field of the Sun is the underlying cause of the many diverse phenomena combined under the heading of solar activity. Here we describe the magnetic field as it threads…
Changes of the solar meridional velocity profile during cycle 23 explained by flows towards the activity belts
R. H. Cameron, M. Schüssler
The solar meridional flow is an important ingredient in Babcock-Leighton type models of the solar dynamo. Global variations of this flow have been suggested to explain the variatio…
Mesogranular structure in a hydrodynamical simulation
Ł. Matloch, R. Cameron, S. Shelyag +2
We analyse mesogranular flow patterns in a three-dimensional hydrodynamical simulation of solar surface convection in order to determine its characteristics. We calculate divergenc…
Simulation of the Formation of a Solar Active Region
M. C. M. Cheung, M. Rempel, A. M. Title +1
We present a radiative magnetohydrodynamics simulation of the formation of an Active Region on the solar surface. The simulation models the rise of a buoyant magnetic flux bundle f…
Surface flux transport modeling for solar cycles 15--21: effects of cycle-dependent tilt angles of sunspot groups
R. H. Cameron, J. Jiang, D. Schmitt +1
We model the surface magnetic field and open flux of the Sun from 1913 to 1986 using a surface flux transport model, which includes the observed cycle-to-cycle variation of sunspot…
The effect of activity-related meridional flow modulation on the strength of the solar polar magnetic field
J. Jiang, E. Isik, R. H. Cameron +2
We studied the effect of the perturbation of the meridional flow in the activity belts detected by local helioseismology on the development and strength of the surface magnetic fie…
The small-scale solar surface dynamo
Jonathan Pietarila Graham, Sanja Danilovic, Manfred Schuessler
The existence of a turbulent small-scale solar surface dynamo is likely, considering existing numerical and laboratory experiments, as well as comparisons of a small-scale dynamo i…
Turbulent small-scale dynamo action in solar surface simulations
Jonathan Pietarila Graham, Robert Cameron, Manfred Schuessler
We demonstrate that a magneto-convection simulation incorporating essential physical processes governing solar surface convection exhibits turbulent small-scale dynamo action. By p…
Probing quiet Sun magnetism using MURaM simulations and Hinode/SP results: support for a local dynamo
S. Danilovic, M. Schuessler, S. K. Solanki
We obtain information about the magnetic flux present in the quiet Sun by comparing radiative MHD simulations with Hinode/SP observations, with particular emphasis on the role of s…
