Temperature Anisotropy in Synthetic Spectroscopic Observations
Abstract
The Alfvén Wave Solar Atmosphere Model (AWSoM), a module within the Space Weather Modeling Framework (SWMF), simulates the entire solar corona in 3D, providing the user with the option of carrying out the calculations assuming either a single plasma temperature, or separate electron and proton (isotropic) temperatures, or separate electron and anisotropic proton temperature (a 3-temperature model). SPECTRUM is a post-processing tool within SWMF, which performs a full synthetic spectral calculation at any wavelength range, with any user-defined spectral resolution. In this work, we investigate the effects of different choices of temperatures (single, 2-temperature, 3-temperature), on the predicted synthetic spectra. The comparison of results will indicate possible diagnostics of temperature anisotropies, which can be observed by solar coronal spectra observed by Hinode/EIS, SoHO/CDS and SUMER, as well as the upcoming SPICE spectrometer on board Solar Orbiter.
