The PDFI_SS Electric Field Inversion Software

George H. Fisher, Maria D. Kazachenko, Brian T. Welsch +5

We describe the PDFI_SS software library, which is designed to find the electric field at the Sun's photosphere from a sequence of vector magnetogram and Doppler velocity measureme…

The role of Alfvén wave dynamics on the large scale properties of the solar wind: comparing an MHD simulation with PSP E1 data

Victor Réville, Marco Velli, Olga Panasenco +18

During Parker Solar Probe's first orbit, the solar wind plasma has been observed in situ closer than ever before, the perihelion on November 6th 2018 revealing a flow that is const…

An in-situ interplanetary "U-burst": Observation and results

Juan Carlos Martínez-Oliveros, Saida Milena Diaz Castillo, Vratislav Krupar +3

We report and examine the observation of an unusual and rare in-situ electron observation associated with a solar type III radio burst on 24 December 1996. This radio event was acc…

Lyman-alpha Variability During Solar Flares Over Solar Cycle 24 Using GOES-15/EUVS-E

Ryan O. Milligan, Hugh S. Hudson, Phillip C. Chamberlin +2

The chromospheric Lyman-alpha line of neutral hydrogen (\lya; 1216Å) is the strongest emission line in the solar spectrum. Fluctuations in \lya\ are known to drive changes in plane…

Laboratory Calibrations of Fe XII-XIV Line-Intensity Ratios for Electron Density Diagnostics

Thusitha P. Arthanayaka, Peter Beiersdorfer, Gregory V. Brown +5

We have used an electron beam ion trap to measure electron-density-diagnostic line-intensity ratios for extreme ultraviolet lines from F XII, XIII, and XIV at wavelengths of 185-20…

Modeling a Carrington-scale Stellar Superflare and Coronal Mass Ejection from

Benjamin J. Lynch, Vladimir S. Airapetian, C. Richard DeVore +5

Observations from the Kepler mission have revealed frequent superflares on young and active solar-like stars. Superflares result from the large-scale restructuring of stellar magne…
