Abstract: We present preliminary results from spectral, timeseries and imaging analysis of all >M5 GOES class flares detected by STIX during the current solar cycle. We carry out spectral fitting of the STIX data, using an automated fitting pipeline built around the python based Sunkit-spex and STIXpy packages. Through forward fitting, we constrain physical parameters that describe both the hot plasma and the energetic electrons which enables us to investigate the thermal vs. non-thermal energy partition during the flaring process across a decade of flare magnitude. Using hard X-ray timeseries analysis of the same sample we investigate the number and timing of electron injection phases, the duration of these episodes and the presence of any quasi periodic oscillations. We also investigate the morphologies of the thermal and non-thermal X-ray sources across the flare duration using the Fourier based imaging techniques in STIXpy. Through this combination of spectral, timeseries and imaging analysis on a large sample of STIX flares, we aim to significantly extend the current understanding of the mechanisms that drive the flaring process.
