Abstract:
The X1.0 flare on March 29, 2014 was well observed, covering its emission at several wavelengths from the photosphere to the corona. The RHESSI spectra images allow us to estimate the temporal variation of the electron spectra using regularized inversion techniques. Using this as input for a combined particle acceleration and transport (Stanford-Flare) and radiative transfer hydrodynamic (Radyn) code, we calculate the response of the atmosphere to the electron heating. We will present the evolution of the thermal continuum and several line emissions. Comparing them with GOES soft X-ray and high resolution observations from IRIS, SDO and DST/IBIS allows us to test the basic mechanism(s) of acceleration and to constrain its characteristics. We will also present perspectives on how to apply this methodology and related diagnostics to other flares.
