Adaptive Hybrid Modeling of Collisionless Plasma Shocks and Ion Acceleration
Yuri A. Omelchenko, Igor V. Sokolov, Lulu Zhao +1
We present a novel efficient technique for hybrid (kinetic ions, quasi-neutral fluid electrons) simulations of non-relativistic magnetized collisionless plasma shocks, frequently o…
SEP-PRISM Data: A multi-source dataset for solar energetic particle forecasting
Yian Yu, Yang Chen, Lulu Zhao +3
Solar energetic particle (SEP) event forecasting often involves integrating heterogeneous observations that differ in cadence, temporal coverage, format, and historical availabilit…
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…
Review of Machine Learning Models for Solar Energetic Particle Prediction
Spiridon Kasapis, Pouya Hosseinzadeh, Kathryn Whitman +73
Solar energetic particle (SEP) events have attracted increasing attention due to their significant radiation hazards for aviation, spacecraft electronics, and human missions beyond…
Realtime forecasting of solar energetic particle event and proton flux using multi-source solar observations and multi-task deep learning
Yian Yu, Yang Chen, Lulu Zhao +3
Solar energetic particle (SEP) events, defined by proton flux exceeding 10 pfu in the > 10 MeV channel, pose major risks to spacecraft operations, astronaut safety, and high-latitu…
