[54.14] FASR Simulation of Solar Flare Microwave Spectrum

J. Lee, D. E. Gary (NJIT), S. M. White (UMd)

We investigate microwave diagnostics on solar flare electrons at the quality of imaging spectroscopy expected from the proposed Frequency Agile Solar Radiotelescope (FASR). We mainly concern ourselves with influence of the spatial inhomogeneities upon microwave spectral features and realistic magnetic configurations of flare active regions. Solar flare microwave radiations are calculated by using nonthermal electrons distributed along a set of reconnected field lines, and by sampling the resulting gyrosynchrotron intensities at the resolution of the FASR. The simulated observations are then compared with reference spectra of homogeneous source models to find a strategy for inversion of the observed spectrum to the physical parameters of flare electrons.

This work is supported by the NSF grant AST-0138317 and NASA grant NAG5-10891 to New Jersey Institute of Technology.
