Mesogranulation and the solar surface magnetic field distribution
L. Yelles Chaouche, F. Moreno-Insertis, V. Martínez Pillet +9
The relation of the solar surface magnetic field with mesogranular cells is studied using high spatial (~ 100 km) and temporal (~ 30 sec) resolution data obtained with the IMaX ins…
Detection of large acoustic energy flux in the solar atmosphere
N. Bello González, M. Franz, V. Martínez Pillet +9
We study the energy flux carried by acoustic waves excited by convective motions at sub-photospheric levels. The analysis of high-resolution spectropolarimetric data taken with IMa…
Surface waves in solar granulation observed with {\sc Sunrise}
M. Roth, M. Franz, N. Bello González +10
Solar oscillations are expected to be excited by turbulent flows in the intergranular lanes near the solar surface. Time series recorded by the IMaX instrument aboard the {\sc Sunr…
SUNRISE/IMaX observations of convectively driven vortex flows in the Sun
J. A. Bonet, I. Marquez, J. Sanchez Almeida +10
We characterize the observational properties of the convectively driven vortex flows recently discovered on the quiet Sun, using magnetograms, Dopplergrams and images obtained with…
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…
Supersonic Magnetic Upflows in Granular Cells Observed with Sunrise/IMaX
J. M. Borrero, V. Martinez Pillet, R. Schlichenmaier +8
Using the IMaX instrument on-board the Sunrise stratospheric balloon-telescope we have detected extremely shifted polarization signals around the Fe I 5250.217 Å spectral line with…
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…
Detection of vortex tubes in solar granulation from observations with Sunrise
O. Steiner, M. Franz, N. Bello Gonzalez +11
We have investigated a time series of continuum intensity maps and corresponding Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the Imag…
Magnetic loops in the quiet Sun
Thomas Wiegelmann, Sami K Solanki, Juan Borrero +9
We investigate the fine structure of magnetic fields in the atmosphere of the quiet Sun. We use photospheric magnetic field measurements from {\sc Sunrise}/IMaX with unprecedented…
The Sunrise Mission
Peter Barthol, Achim Gandorfer, Sami K. Solanki +42
The first science flight of the balloon-borne \Sunrise telescope took place in June 2009 from ESRANGE (near Kiruna/Sweden) to Somerset Island in northern Canada. We describe the sc…
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…
The Filter Imager SuFI and the Image Stabilization and Light Distribution System ISLiD of the Sunrise Balloon-Borne Observatory: Instrument Description
A. Gandorfer, B. Grauf, P. Barthol +29
We describe the design of the Sunrise Filter Imager (SuFI) and the Image Stabilization and Light Distribution (ISLiD) unit onboard the Sunrise balloon borne solar observatory. This…
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,…
Where the granular flows bend
E. Khomenko, V. Martinez Pillet, S. K. Solanki +7
Based on IMaX/Sunrise data, we report on a previously undetected phenomenon in solar granulation. We show that in a very narrow region separating granules and intergranular lanes t…
