CORHEL-CME: An Interactive Tool For Modeling Solar Eruptions
Jon Linker, Tibor Torok, Cooper Downs +5
Coronal Mass Ejections (CMEs) are immense eruptions of plasma and magnetic fields that are propelled outward from the Sun, sometimes with velocities greater than 2000 km/s. They ar…
Global MHD Simulations of the Time-Dependent Corona
Roberto Lionello, Cooper Downs, Emily I. Mason +5
We describe, test, and apply a technique to incorporate full-sun, surface flux evolution into an MHD model of the global solar corona. Requiring only maps of the evolving surface f…
Prediction and Verification of Parker Solar Probe Solar Wind Sources at 13.3 R
Samuel T. Badman, Pete Riley, Shaela I. Jones +11
Drawing connections between heliospheric spacecraft and solar wind sources is a vital step in understanding the evolution of the solar corona into the solar wind and contextualizin…
Modeling CME encounters at Parker Solar Probe with OSPREI: Dependence on photospheric and coronal conditions
Vincent E. Ledvina, Erika Palmerio, Christina Kay +2
Context: Coronal mass ejections (CMEs) are eruptions of plasma from the Sun that travel through interplanetary space and may encounter Earth. CMEs often enclose a magnetic flux rop…
Quantifying errors in 3D CME parameters derived from synthetic data using white-light reconstruction techniques
Christine Verbeke, M. Leila Mays, Christina Kay +10
(Shortened version) Current efforts in space weather forecasting of CMEs have been focused on predicting their arrival time and magnetic structure. To make predictions, methods hav…
A data-driven physics-based transport model of solar energetic particles accelerated by coronal mass ejection shocks propagating through the solar coronal and heliospheric magnetic fields
Ming Zhang, Lei Cheng, Ju Zhang +5
In an effort to develop computational tools for predicting radiation hazards from solar energetic particles (SEPs), we have created a data-driven physics-based particle transport m…
Coronal mass ejection deformation at 0.1 au observed by WISPR
Carlos R. Braga, Angelos Vourlidas, Paulett C. Liewer +3
Although coronal mass ejections (CMEs) resembling flux ropes generally expand self-similarly, deformations along their fronts have been reported in observations and simulations. We…
Constraining Global Coronal Models with Multiple Independent Observables
Samuel T. Badman, David H. Brooks, Nicolas Poirier +13
Global coronal models seek to produce an accurate physical representation of the Sun's atmosphere which can be used, for example, to drive space weather models. Assessing their acc…
Energetic Proton Propagation and Acceleration Simulated for the Bastille Day Event of July 14, 2000

This work presents results from simulations of the 14 July 2000 ("Bastille Day") solar proton event. We used the Energetic Particle Radiation Environment Model (EPREM) and the CORo…
Solar Sources of Interplanetary Magnetic Clouds Leading to Helicity Prediction
Roger K. Ulrich, Pete Riley, T. Tran
This study identifies the solar origins of magnetic clouds that are observed at 1 AU and predicts the helical handedness of these clouds from the solar surface magnetic fields. We…
Sun-to-Earth MHD Simulation of the 14 July 2000 "Bastille Day" Eruption
Tibor Török, Cooper Downs, Jon A. Linker +6
Solar eruptions are the main driver of space-weather disturbances at the Earth. Extreme events are of particular interest, not only because of the scientific challenges they pose,…
The Open Flux Problem
J. A. Linker, R. M. Caplan, C. Downs +9
The heliospheric magnetic field is of pivotal importance in solar and space physics. The field is rooted in the Sun's photosphere, where it has been observed for many years. Global…
Origins of the Ambient Solar Wind: Implications for Space Weather
Steven R. Cranmer, Sarah E. Gibson, Pete Riley
The Sun's outer atmosphere is heated to temperatures of millions of degrees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our curre…
