Coronal Densities, Temperatures, and Abundances during the 2019 Total Solar Eclipse: The Role of Multiwavelength Observations in Coronal Plasma Characterization
Del Zanna, Giulio; DeLuca, Edward; Mason, Helen +7 more
The Airborne Infrared Spectrometer (AIR-Spec) offers an unprecedented opportunity to explore the near-infrared (NIR) wavelength range. It has been flown at two total solar eclipses, in 2017 and 2019. The wavelength range of the much-improved instrument on the second flight (2019 July 2) was shifted to cover two density-sensitive lines from S XI. I…
Slow Solar Wind Connection Science during Solar Orbiter's First Close Perihelion Passage
D'Amicis, Raffaella; Teriaca, Luca; Hirzberger, Johann +76 more
The Slow Solar Wind Connection Solar Orbiter Observing Plan (Slow Wind SOOP) was developed to utilize the extensive suite of remote-sensing and in situ instruments on board the ESA/NASA Solar Orbiter mission to answer significant outstanding questions regarding the origin and formation of the slow solar wind. The Slow Wind SOOP was designed to lin…
Large-scale Spatial Cross-calibration of Hinode/SOT-SP and SDO/HMI
Liu, Yang; Antiochos, Spiro K.; Leka, K. D. +7 more
We investigate the cross-calibration of the Hinode/Solar Optical Telescope-Spectro-Polarimeter (SOT-SP) and Solar Dynamics Observatory/Helioseismic and Magnetic Imager (SDO/HMI) instrument metadata, specifically the correspondence of the scaling and pointing information. Accurate calibration of these data sets gives the correspondence needed by in…
Nonequilibrium Ionization Effects on Synthetic Spectra in the AWSoM Solar Corona
Landi, E.; van der Holst, B.; Szente, J.
In this work, we combined AWSoM's nonequilibrium ionization (NEI) calculations from Szente et al. with the synthetic spectral computations of SPECTRUM to predict nonequilibrium line intensities across the entire domain of the AWSoM 3D global model. We find that the resulting spectra are strongly affected by nonequilibrium effects in the fast-wind …
