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 W…
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…
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…
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…
Counterintuitive Magnetic Connectivity and Energetic Particle Flux Differences among Nearby Spacecraft During the 2023 February 24 Solar Energetic Particle Event
Weihao Liu, Xianyu Liu, David Lario +4
For solar energetic particles (SEPs), it is generally expected that observers magnetically closer to the eruption source region exhibit higher particle intensities than those poorl…
Defects and Inconsistencies in Solar Flare Data Sources: Implications for Machine Learning Forecasting
Ke Hu, Kevin Jin, Victor Verma +5
Machine learning models for forecasting solar flares have been trained and evaluated using a variety of data sources, including Space Weather Prediction Center (SWPC) operational a…
Solar Energetic Particle Forecasting with Multi-Task Deep Learning: SEPNET
Yian Yu, Yang Chen, Lulu Zhao +3
Solar energetic particle (SEP) events pose severe threats to spacecraft, astronaut safety, and aviation operations. Accurate SEP forecasting remains a critical challenge in space w…
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…
Simulating the Solar Corona with Multiple Solar Photospheric Magnetic Maps during the 8 April 2024 Total Solar Eclipse
Xianyu Liu, Weihao Liu, Ward B. Manchester +11
The 8 April 2024 total solar eclipse (TSE) provides a unique opportunity to study the solar corona. This work presents our simulations of the solar corona at the time of the eclips…
Toward quantitative model for simulation and forecast of solar energetic particle production during gradual events -- II: kinetic description of SEP
D. Borovikov, I. V. Sokolov, Z. Huang +2
Solar Energetic Particles (SEPs) possess a high destructive potential as they pose multiple radiation hazards on Earth and onboard spacecrafts. The present work continues a series…
Magnetized jets driven by the sun: the structure of the heliosphere revisited
M. Opher, J. F. Drake, B. Zieger +1
The classic accepted view of the heliosphere is a quiescent, comet-like shape aligned in the direction of the Sun's travel through the interstellar medium (ISM) extending for 1000'…
A Steady-State Picture of Solar Wind Acceleration and Charge State Composition Derived from a Global Wave-Driven MHD Model
Rona Oran, Enrico Landi, Bart van der Holst +7
The higher charge states found in slow (400km s) solar wind streams compared to fast streams have supported the hypothesis that the slow wind originates in closed coronal…
