Description

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 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 25,000 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.
