Large-sample STIX analysis and X-ray diagnostics

Talk

In the framework of the Horizon Europe project SOLER (Energetic Solar Eruptions: Data and Analysis Tools) we are leading the work package on X-ray data analysis. I will discuss some of our results as well as work in progress. This will include (1) STIX spectroscopy for all >M5 flares of the current solar cycle, (2) STIX timeseries analysis of a larger sample of flares using Gaussian...

Large-sample STIX analysis and X-ray diagnostics

Talk

Using Sunkit-spex alongside STIXpy, it is now possible, for the first time, to carry out a complete Python based STIX spectroscopic analysis. We present preliminary results of the spectral analysis of a sample of >M5 GOES class flares from the current solar cycle as observed by STIX. We use an automated fitting pipeline to constrain the evolution of key thermal and non-thermal parameters,...

Large-sample STIX analysis and X-ray diagnostics

Talk

Recent observations by the Spectrometer/Telescope for Imaging X-rays (STIX) onboard Solar Orbiter have revealed deviations from the classical energy-altitude relation of hard X-ray (HXR) footpoint sources in solar flares. While the standard thick-target model predicts monotonic decrease of source height with increasing energy, STIX observations show non-monotonic features, including local...
