The Working Group "Space-based Astrophysics" deals with multi-wavelength observations aiming at understanding the formation and evolution of cool stars and works experimentally in the field of ultraviolet (UV) astronomy.
Projects: Space-based Astrophysics
Space-based Astrophysics focuses on following projects:
Identification of flare stars among variable X-ray sources
X-ray flares on young stars
Origin of the X-ray emission in accreting low-mass stars
Magnetic activity on ultracool dwarfs
Projects: UV-detector development
In the field of UV-detector development the following topics are addressed:
Development of the detector electronics (FPGA programming)
Evaluation of different algorithms for the analysis of detector signals
Development of new photo cathodes (growth of thin films (photocathodes) and steps to improve the quantum efficiency: from the light absorption of UV-light to the emission of photoelectrons)
Improvement of the detector (sealing the detector body under ultra-high vacuum, optimizing the sealing areas and further steps to produce space qualified imaging detectors)
