Studying Coronal Heating with Data Driven Active Region Modeling using GX Simulator
Abstract
Recent upgrades to the GX Simulator data driven active region modeling IDL (Interactive Data Language) tool integrating the EBTEL (Enthalpy-Based Thermal Evolution of Loops) coronal loop model allow for detailed analysis of the impact of coronal heating parameterization on observations. We test this new capability using a unique set of simultaneous observations of active region NOAA 11809 in the X-ray, extreme ultraviolet (EUV), and microwave collected with Hinode, the Solar Dynamics Observatory, and the Very Large Array (VLA). Photospheric magnetic field measurements are extrapolated into the corona using NLFFF (non-linear force-free field) techniques and then coronal plasma is populated using EBTEL models run assuming various coronal heating prescriptions. Emission from the active region is then simulated and compared to the many available observations. We present initial results comparing multiple heating parameterizations and discuss the implications of these findings on the nature of coronal heating properties.
