Franz-Ludwig Deubner passed away on 21 October 2017 in Freiburg. He had been a member of the Editorial Board of Solar Physics and President of IAU Commission 12 Solar Radiation & Structure. His accomplishments and many contributions to the field of solar physics are well remembered.

 

Franz was born on 2 June 1934 in Berlin, Germany. His father Alex was a physicist, his mother Louise (née Wegener) a pianist. After graduating from a “Humanistisches Gymnasium”, Franz studied physics and mathematics at the Technical University of Berlin (1953 – 1956) and the University of Freiburg (1956 – 1958), where he received his “Diplom” in 1958. He then joined the scientific staff at the Fraunhofer Institute in Freiburg (since 1978 called Kiepenheuer Institute), where he built a vector magnetograph for the institute’s Schauinsland observatory (1959 – 1960). In 1962 K.O. Kiepenheuer started the expansion of the institute’s Capri Station, for which Franz developed a new magnetograph. It was installed at the new domeless Coudé refractor in 1966. Franz had not only designed this architecturally remarkable telescope (together with his wife), he had also programmed the Siemens control computer of the telescope and magnetograph, a novelty in astronomy at that time. A key component of this magnetograph was the “Doppler-Kompensator”, an electro-mechanical control mechanism that kept the spectral line centered on a pair of photomultipliers, allowing a precise measurement of the linear and circular polarization of the line. The angle of the rotating glass plate of this device provided an excellent measure of the line’s Doppler shift, and Franz began to study the recently discovered solar oscillations in more detail. Franz received his PhD in January 1969, based on data obtained with this instrument.

 

Probably his most profound contribution to the field of solar physics was his seminal 1975 paper (...

The data archive of the GREGOR infrared spectrograph (GRIS, Collados et al. 2012, AN 333, 872) is online now. GRIS data prior to 2017 is open access and now available through the GRIS data archive. It contains more than 500 data sets recorded in the years between 2014 and 2016. Most of them are single raster scans recorded in spectropolarimetric mode in the 1.08µm and 1.56µm wavelength bands. Some of them are measurements in spectroscopic mode, time sequences capturing the evolution of solar features, and observation in other wavelength bands such as 2.2µm.

Wir trauern um Dr. Joachim Staiger, der am 28. Februar 2017 plötzlich und unerwartet verstorben ist.

Herr Dr. Staiger studierte Physik an der Universität Freiburg, wo er 1975 das Staatsexamen für den Gymnasialunterricht in Mathematik und Physik ablegte, und zusätzlich im Mai 1978 das Diplom in Physik erwarb. Er gehörte dem damaligen Fraunhofer-Institut (und heutigem Kiepenheuer-Institut) seit 1976 an; seit 1983 als Wissenschaftlicher Mitarbeiter. 1985 promovierte Herr Staiger an der Universität Freiburg zu dem Thema „Wellenausbreitung in der Sonnenatmosphäre“, betreut von Franz Ludwig Deubner und Wolfgang Mattig. Seit Februar 2016 formell im Ruhestand, war Herr Dr. Staiger bis zuletzt in die Aktivitäten des Instituts intensiv involviert.

Joachim Staiger war Helioseismologe und Instrumentenentwickler. Er begann seine Karriere am Sonnenobservatorium auf Capri, wo er die Ausbreitung der Fünf-Minuten-Oszillationen in den oberen Schichten der Sonnenatmosphäre mithilfe eines von ihm entwickelten Detektors untersuchte. Er wurde früh in den Aufbau des Observatoriums auf Teneriffa, welches das Capri-Observatorium ablöste, eingebunden. Seitdem war er für die Steuerung des Vakuum-Turmteleskops verantwortlich, welche er mit innovativer Inspiration und außergewöhnlich hohem Einsatz auf dem neuesten Stand hielt. Zu seinen Pionierleistungen gehört die Entwicklung und Wartung der Steuerung über das Internet, was ihm erlaubte, bei Problemen von überall und jederzeit helfend einzugreifen. Er kehrte in den vergangenen zehn Jahren zu seinen wissenschaftlichen Ursprüngen zurück und entwickelte mit HELLRIDE ein einzigartiges und begehrtes Instrument zur Untersuchung von Wellen in der Sonnenatmosphäre. Joachim Staiger war für viele Jahre der Vorsitzende des Personalrats des Instituts.

Wir werden Joachim Staiger mit seinem freundlichen und zurückhaltenden Wesen, mit seinem unermüdlichen Einsatz für die Belange des Instituts und seiner Mitarbeiter und Mitarbeiterinnen, sowie mit seiner selbstlosen Hilfsbereitschaft in Erinnerung behalten. Ein guter Geist des Vakuum-Turmteleskops ist von uns gegangen. Wir werden ihn vermissen.

On November 19, 2015, Prof. Dr. Matthias Kleiner, the President of the Leibniz Association, paid a visit to the Kiepenheuer-Institut, in the company of scientific officer Dr. Karin Effertz.

The delegation held discussions with the board, leading staff members and young scientists.

The focus of the visit was on the importance of solar physics for science and society, prospects for young scientists in Germany, and the physical accommodation of the institute. Prof. Kleiner pointed out that his role in the Leibniz Association is to help institutes achieve their goals.

The 3rd SOLARNET / 7th HELAS / SpaceInn international conference "The Sun, the stars, and Solar-stellar relations" will take place in Freiburg (Germany) between 31 August - 4 September 2015, organized by the Kiepenheuer-Institut für Sonnenphysik (KIS). SOLARNET (High-resolution Solar Physics Network) is an international project promoted by the European Association for Solar Telescopes (EAST) and funded by the European Commission FP7. HELAS is the European Helio- and Asteroseismology Network, which aims at coordinating the activities of the research groups active in helio-and asteroseismology. The purpose of this conference is to discuss the latest questions and results in solar and stellar physics. Solar and stellar seismology will be one particular focus but contributions on all aspects of solar-stellar relations will be welcome. We aim to establish links and synergies between the day- and night-time fields of astrophysics. In detail the following topics will be addressed in individual sessions as showed in the Scientific Program. Furthermore new and upcoming projects and missions shall be presented. Graduate students and early-career postdocs are particularly invited to participate in the conference to present their research work and to meet and discuss with their more senior colleagues. A limited amount of financial resources shall be available to grant travel support. Contact: mroth(at)leibniz-kis.de...
