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...
The Sunrise Ultraviolet Spectropolarimeter and Imager: Instrument Description
The third science flight of the balloon-borne solar observatory SUNRISE carries three entirely new post-focus science instruments with spectropolarimetric...
The Temperature - Magnetic Field Relation in Observed and Simulated Sunspots
Observations of the relation between continuum intensity and magnetic field strength in sunspots have been made for nearly five decades. This work presents full...
The Wave-Front Correction System for the Sunrise Balloon-Borne Solar Observatory
This paper describes the wave-front correction system developed for the Sunrise balloon telescope, and it provides information about its in-flight performance...
Tomographic Reconstruction of the Solar K-Corona Using Neural Fields
We explore the application of neural fields for tomographic reconstructions of the solar corona using data from the Large Angle and Spectrometric Coronagraph...
Transport Effects in the Evolution of the Global Solar Magnetic Field
The axisymmetric component of the large-scale solar magnetic fields has a pronounced poleward branch at higher latitudes. In order to clarify the origin of this...
Tri-Phonic Helioseismology: Comparison of Solar P Modes Observed by the Helioseismology Instruments Aboard SOHO
The three helioseismology instruments aboard SOHO observe solar p modes in velocity (GOLF and MDI) and in intensity (VIRGO and MDI). Time series of two months...
TuMag: The Tunable Magnetograph for the SUNRISE III Mission
SUNRISE III is a balloon-borne solar observatory dedicated to the investigation of the processes governing the physics of the magnetic field and the plasma...
Variation of the low-degree solar acoustic mode parameters over the solar cycle
VIRGO/SPM is a helioseismic sunphotometer on board SOHO that observes the disk-integrated sunlight irradiance at three different colors (red, green, and blue)...
