Tracking Magnetic Topological Change in a Time-Dependent Coronal Model
Emily I. Mason, Cooper Downs, Roberto Lionello +2
We apply the slip-back mapping method of Titov et al. 2009 and Lionello et al. 2020 to a thermodynamic MHD simulation to track topological changes in the magnetic field at a range…
Magnetic Connectivity in the Time-Dependent Corona and Heliosphere
Roberto Lionello, Cooper Downs, Emily I. Mason +3
Magnetic flux fills the heliosphere, expands outward from the solar corona, and is fundamentally related to the structure and dynamics of the solar corona and solar wind. Open magn…
Evolution of Spatial Complexity in Flare Ribbon Substructure and Its Relationship to Magnetic Reconnection Dynamics
Marcel F. Corchado Albelo, Maria D. Kazachenko, Ryan J. French +5
Recent three-dimensional flare models suggest that flare-ribbon substructure is linked to the fragmentation of the reconnecting current sheet in the corona. Flare-ribbon substructu…
Statistical Overview of Long-Lived Active Regions Observed Across Multiple Carrington Rotations
Emily I. Mason, Kara L. Kniezewski
The study of solar active regions (ARs) is of central importance to a range of fundamental science, as well as the practical applications of space weather. Active region emergence…
Magnetic Field Variability as a Consistent Predictor of Solar Flares
Kara L. Kniezewski, Emily I. Mason, Daniel J. Emmons +2
Solar flares are intense bursts of electromagnetic radiation, which occur due to a rapid destabilization and reconnection of the magnetic field. While pre-flare signatures and tren…
