The KIS carries out fundamental research in astronomy and astrophysics with a particular focus on solar physics and is a member of the Leibniz Association . We are leading the sunscreens at the Observatorio del Teide in Tenerife, as well as the old solar observatory on the Schauinsland near Freiburg. We also offer lectures at the University of Freiburg and train young academics. In 1985, Mr. Staiger at the University of Freiburg promoted the topic of "wave propagation in the solar atmosphere", supervised by Franz Ludwig Deubner and Wolfgang Mattig. Since formally retired in February 2016, Dr. Staiger has been intensively involved in the activities of the institute.Joachim Staiger was a helioseismologist and instrument developer. He began his career at the Sun Observatory at Capri, where he investigated the spread of five-minute oscillations in the upper layers of the solar atmosphere using a detector he developed. He was involved early in the construction of the Observatory on Tenerife, which replaced the Capri observatory. Since then, he has been responsible for the control of the vacuum tower telescope, which he has kept up to date with innovative inspiration and exceptional use. His pioneering efforts included the development and maintenance of the control system over the Internet, which allowed him to intervene with problems from anywhere and at any time. He has returned to his scientific origins over the past ten years and developed a unique and sought-after instrument for the investigation of waves in the solar atmosphere with HELLRIDE. For many years, Joachim Staiger was the chairman of the Institutes staff council. Astrophysical basic research in the area of solar physics is the central task of the Kiepenheuer Institute for Solar Physics (KIS). The research work of the KIS is divided into Theoretical Solar Physics and Experimental Solar Physics, including the operation of the German solar telescopes at the Observatorio del Teide, Tenerife, and the instrumental development. The topics and objectives of our work are divided into four research areas, which cover both theoretical and experimental work. The system of solar magnetism plays the connecting role. CASSDA : The CASSDA project - Centre for Advanced Solar Spectro-polarimetric Data Analysis - is conceived to provide to the solar physics community with accurate spectroscopic and spectro-polarimetric datasets observed at the German telescopes. EAST : The European Association for Solar Telescopes (EAST) was founded in 2006 by a group of solar physicists from 14 European countries. The goal of EAST is to ensure access of European solar astronomers to world-class high-resolution ground-based observing facilities. HotMol: This project develops several exploratory theoretical and observational aspects of precision spectropolarimetry for detecting water vapour and other volatiles on exoplanets and in the inner part of protoplanetary disks. InnoPol : Polarimetry is a powerful technique for revealing two- and three-dimensional structures in astrophysical objects beyond the spatial resolution provided by direct imaging at any telescope. ORIGIN : The core of this project is to gain insight in the processes that are of major relevance for the solar dynamo by novel and improved methods of helioseismology. The analyses go far beyond the state-of-the-art and are based on highly resolved velocity measurements on the Sun from NASA’s milestone missions SOHO and SDO as well as the instruments of the GONG network. SOLARNET : SOLARNET brings together and integrates the major European research infrastructures in the field of high-resolution solar physics, in order to promote their coordinated use and development. SolarOrbiter-ISS : Solar Orbiter ist eine ESA Mission zur Beobachtung der Sonne bei hoher räumlicher Auflösung und für in-situ Messungen der Heliosphäre sehr nahe der Sonne. SpaceInn : The European Helio- and Asteroseismology Network (HELAS) has initiated the project "Exploitation of Space Data for Innovative Helio- and Asteroseismology - SpaceInn" with the mission to build on the existing European strength in the field of time-domain stellar physics. Sunrise : Sunrise ist ein ballongetragenes Sonnenteleskop mit einer Öffnung von einem Meter. Es wird die Sonne im sichtbaren und nah-ultravioletten Licht beobachten (400 bis 215 nm). Visible Tunable Filter : The Visible Tunable Filter (VTF) for the Daniel K. Inouye Solar Telescope is an imaging spectro-polarimeter for the wavelength range between 520 and 860 nm. It operates at the highest spatial resolution possible for the DKIST, 20 km on the Sun, equivalent to an angular resolution of 0.028 arcseconds.
