The SUNRISE UV Spectropolarimeter and imager for SUNRISE III

Ground-based and Airborne Instrumentation for Astronomy VIII, 2020
Sunrise is a balloon-borne solar observatory dedicated to the investigation of key processes of the magnetic field and the plasma flows in the lower solar atmosphere. The observatory operates in the stratosphere at an altitude of around 37 km in order to avoid image degradation due to turbulence in the Earth’s atmosphere and to access the UV range. The

The Sun Radio Interferometer Space Experiment (SunRISE) Mission

IEEE Aerospace Conference, 2021
The Sun Radio Interferometer Space Experiment (SunRISE) will provide an entirely new view on particle acceleration and transport in the inner heliosphere by creating the first low radio frequency interferometer in space to localize heliospheric radio ...

Sunrise Chromospheric Infrared SpectroPolarimeter (SCIP) for sunrise III: system design and capability

Ground-based and Airborne Instrumentation for Astronomy VIII, 2020
The Sunrise balloon-borne solar observatory carries a 1 m aperture optical telescope and provides us a unique platform to conduct continuous seeing-free observations at UV-visible-IR wavelengths from an altitude of higher than 35 km.

Sunrise strategy for the continuity of maximal operators

Journal d'Analyse Mathematique, 2020
In this paper we address the $W^{1,1}$-continuity of several maximal operators at the gradient level. A key idea in our global strategy is the decomposition of a maximal operator, with the absence of strict local maxima in the disconnecting set, into ...

The Physical Mechanisms for the Sunrise Enhancement of Equatorial Ionospheric Upward Vertical Drifts

Journal of Geophysical Research: Space Physics, 2020
Satellite and incoherent scatter radar observations have shown frequently a strong enhancement of upward vertical E × B drifts in the equatorial ionospheric F region near sunrise.

Sunrise on the pines

Applied Optics, 2020
As the sun rises above a mountain ridge populated with pine trees, a short-lived but spectacular light scattering effect off the pine needles is visible. It was noted by the Victorian physicist and mountaineer John Tyndall in his two mountaineering books, and this paper describes Tyndall’s observations, discusses his and Professor Necker’s descriptions,

Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) for SUNRISE-3: polarization modulation unit

Ground-based and Airborne Instrumentation for Astronomy VIII, 2020
Polarization measurements of the solar chromospheric lines at high precision are key to present and future solar telescopes for understanding magnetic field structures in the chromosphere.
