The Effects of Energy Conservation in Simulating Solar Eruptions
Xianyu Liu, Spiro K. Antiochos, Nishtha Sachdeva +6
Strict energy conservation is, perhaps, the most basic principle in all physics, but has proven to be difficult to satisfy in numerical simulations of solar eruptions. The Alfvén…
Effects of the Background Magnetic Field on Flux Rope Eruptions
Xianyu Liu, Spiro K. Antiochos, Igor V. Sokolov +5
Solar eruptive events are generally believed to involve magnetic flux ropes (MFR), formed either in the pre-eruptive phase of the event or during the eruption itself. These MFR eru…
Simulated Operational Testing of the Prototype Implementation of the SOFIE Model: The 2025 Space Weather Prediction Testbed Exercise
Weihao Liu, Lulu Zhao, Igor V. Sokolov +29
The CLEAR Space Weather Center of Excellence's solar energetic particle (SEP) model, SOlar wind with FIeld lines and Energetic particles (SOFIE), was run and evaluated on-site duri…
Evolution of Coronal Mass Ejections in Different Data-Driven Solar Wind Conditions
Nishtha Sachdeva, Zhenguang Huang, Gabor Toth +3
Numerical models of the solar wind and coronal mass ejections (CMEs) utilize photospheric magnetic field observations to prescribe the inner boundary conditions for the plasma solu…
Evidence of Time-Dependent Diffusive Shock Acceleration in the 2022 September 5 Solar Energetic Particle Event
Xiaohang Chen, Lulu Zhao, Joe Giacalone +15
On 2022 September 5, a large solar energetic particle (SEP) event was detected by Parker Solar Probe (PSP) and Solar Orbiter (SolO), at heliocentric distances of 0.07 and 0.71 au,…
Physics-Based Simulation of the 2013 April 11 Solar Energetic Particle Event
Weihao Liu, Igor V. Sokolov, Lulu Zhao +11
Solar energetic particles (SEPs) can pose hazardous radiation risks to both humans and spacecraft electronics in space. Numerical modeling based on first principles offers valuable…
