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…
