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…
Auto-Calibration of Remote Sensing Solar Telescopes with Deep Learning
Brad Neuberg, Souvik Bose, Valentina Salvatelli +6
As a part of NASA's Heliophysics System Observatory (HSO) fleet of satellites,the Solar Dynamics Observatory (SDO) has continuously monitored the Sun since2010. Ultraviolet (UV) an…
Using U-Nets to Create High-Fidelity Virtual Observations of the Solar Corona
Valentina Salvatelli, Souvik Bose, Brad Neuberg +6
Understanding and monitoring the complex and dynamic processes of the Sun is important for a number of human activities on Earth and in space. For this reason, NASA's Solar Dynamic…
The Multi-slit Approach to Coronal Spectroscopy with the Multi-slit Solar Explorer (MUSE)
Bart De Pontieu, Juan Martinez-Sykora, Paola Testa +6
The Multi-slit Solar Explorer (MUSE) is a proposed mission aimed at understanding the physical mechanisms driving the heating of the solar corona and the eruptions that are at the…
Three-dimensional modeling of chromospheric spectral lines in a simulated active region
Johan P. Bjørgen, Jorrit Leenaarts, Matthias Rempel +4
Because of the complex physics that governs the formation of chromospheric lines, interpretation of solar chromospheric observations is difficult. The origin and characteristics of…
Machine learning reveals systematic accumulation of electric current in lead-up to solar flares
Dattaraj B. Dhuri, Shravan M. Hanasoge, Mark C. M. Cheung
Solar flares - bursts of high-energy radiation responsible for severe space-weather effects - are a consequence of the occasional destabilization of magnetic fields rooted in activ…
