The Leibniz-Institute for Astrophysics Potsdam (AIP) invites applications for a Doctoral Student (m/f/d) in Solar Physics. The doctoral student will work on well-defined research projects to investigate several aspects of solar activity using observational data from ESA’s recent Solar Orbiter mission. AIP is involved in two of the instruments on board, i.e., the X-ray telescope STIX and the particle detector EPD. Therefore, the focus of research will be on studying solar flares and the associated energetic particles, primarily using X-ray data.
