Project Description: 

WE AIM TO (A) INVESTIGATE THE PHYSICAL MECHANISMS DRIVING SOLAR ACTIVE REGION (AR) ERUPTIONS (B) PROVIDE A CRITICAL EVALUATION OF THE VALIDITY OF REMOTE SENSING TECHNIQUES THAT AIM TO QUANTIFY THE ERUPTIVE POTENTIAL OF ARS AND (C) DEVELOP A DATA-DRIVEN MHD MODEL OF SOLAR ERUPTIONS WITH SYNTHETIC OBSERVABLES DIRECTLY COMPARABLE TO ACTUAL OBSERVED DATA. TO REACH THESE GOALS THIS THEORY/MODELING/ SIMULATION (TMS) EFFORT CONSISTS OF THE FOLLOWING ELEMENTS: (1) STATE-OF-THE-ART 3D RADIATIVE MHD SIMULATIONS OF SOLAR ERUPTIONS - THESE MODELS WILL BE DRIVEN BY THE EMERGENCE AND SUBSEQUENT EVOLUTION OF MAGNETIC FLUX THAT EVENTUALLY FORMS ARS. THEY WILL COVER A REGION SPANNING FROM THE UPPER LAYERS OF THE CONVECTION ZONE TO THE OVERLYING ATMOSPHERE (INCLUDING THE CORONA) AND INCLUDE THE NECESSARY PHYSICS (E.G. TIME-DEPENDENT HYDROGEN IONIZATION REALISTIC EQUATION OF STATE NON-LTE RADIATIVE ENERGY EXCHANGE FIELD-ALIGNED THERMAL CONDUCTION IN THE CORONA ETC). (2) ADVANCED DIAGNOSTICS FROM FORWARD-MODELING OF ATMOSPHERIC OBSERVABLES WE WILL DEVELOP TOOLS THAT PROVIDE DIAGNOSTICS FOR ALL REGIONS OF THE SOLAR ATMOSPHERE NAMELY THE PHOTOSPHERE CHROMOSPHERE TRANSITION REGION AND CORONA. THE TOOLS WILL PRODUCE SYNTHETIC IMAGES AND SPECTRA TO COMPARE WITH DATA FROM NASA'S SOLAR MISSIONS (E.G. IRIS SDO HINODE) AND GROUND-BASED OBSERVATORIES. (3) VALIDATED DATA-DRIVEN MODELS OF ARS - WE WILL BENCHMARK MODELS OF AR MAGNETIC FIELDS BASED ON NON-LINEAR FORCE-FREE FIELD EXTRAPOLATION (NLFFF) AND MAGNETOFRICTION (MF) TECHNIQUES AGAINST REAL OBSERVATIONS AND RADIATIVE MHD SIMULATIONS. THESE TECHNIQUES WILL THEN BE USED TO MODEL THE EVOLUTION OF OBSERVED ARS. SYNTHETIC OBSERVABLES CALCULATED FROM THE MODELS WILL BE DIRECTLY COMPARED AGAINST OBSERVATIONS FROM THE PHOTOSPHERE TO CORONA. (4) METRICS FOR THE ERUPTIVE POTENTIAL OF ARS - WE WILL COMBINE ELEMENTS (1) (3) AND EVALUATE PHYSICS-MOTIVATED METRICS THAT PROBE THE ERUPTIVE POTENTIAL OF ARS. THESE INCLUDE METRICS DERIVED FROM PHOTOSPHERIC/CHROMOSPHERIC MAGNETOGRAMS AND FROM CORONAL/ TRANSITION REGION SPECTRA.
