Studying solar flares with the X-ray telescope STIX during the cruise and early science phase of Solar Orbiter — •Alexander Warmuth — Leibniz-Institut für Astrophysik Potsdam (AIP)

Of the six remote-sensing instruments aboard Solar Orbiter, the Spectrometer/Telescope for Imaging X-rays (STIX) is the one dedicated to the study of solar flares. It performs X-ray imaging spectroscopy in the hard X-ray regime, which provides key physical diagnostics on both the hot thermal plasma as well as on the accelerated energetic electrons. During its operation since launch in 2020, which now includes the first year of the nominal mission phase, STIX has detected over 10000 solar flares. The first scientific results based on these novel observations will be discussed. In particular, we will focus on studies that use STIX jointly with other observational assets, such as the other remote-sensing instruments on Solar Orbiter, various X-ray instruments on other spacecraft, and in-situ particle detectors.
