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…
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,…
Solar Wind with Field Lines and Energetic Particles (SOFIE) Model: Application to Historical Solar Energetic Particle Events
Lulu Zhao, Igor Sokolov, Tamas Gombosi +7
In this paper, we demonstrate the applicability of the data-driven and self-consistent solar energetic particle model, Solar-wind with FIeld-lines and Energetic-particles (SOFIE),…
Three-dimensional, Time-dependent MHD Simulation of Disk-Magnetosphere-Stellar Wind Interaction in a T Tauri, Protoplanetary System
Ofer Cohen, Cecilia Garraffo, Jeremy Drake +4
We present a three-dimensional, time-dependent, MHD simulation of the short-term interaction between a protoplanetary disk and the stellar corona in a T Tauri system. The simulatio…
Solar wind modeling with the Alfven Wave Solar atmosphere Model driven by HMI-based Near-Real-Time maps by the National Solar Observatory
Nishtha Sachdeva, Ward B Manchester, Igor Sokolov +6
We explore model performance for the Alfven Wave Solar atmosphere Model (AWSoM) with near-real-time (NRT) synoptic maps of the photospheric vector magnetic field. These maps, produ…
Modeling the Solar Wind During Different Phases of the Last Solar Cycle
Zhenguang Huang, Gabor Toth, Nishtha Sachdeva +5
We describe our first attempt to systematically simulate the solar wind during different phases of the last solar cycle with the Alfvén Wave Solar atmosphere Model (AWSoM) develope…
Application of the Monte Carlo Method in Modeling Transport and Acceleration of Solar Energetic Particles
Valeriy Tenishev, Lulu Zhao, Igor Sokolov
The need for quantitative characterization of the solar energetic particle (SEP) dynamics goes beyond being an academic discipline only. It has numerous practical implications rela…
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…
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…
Alfven Wave Solar Model (AWSoM): Coronal Heating
Bart van der Holst, Igor V. Sokolov, Xing Meng +4
We present a new version of the Alfven Wave Solar Model (AWSoM), a global model from the upper chromosphere to the corona and the heliosphere. The coronal heating and solar wind ac…
Probing the Edge of the Solar System: Formation of an Unstable Jet-Sheet
M. Opher, P. C. Liewer, T. I. Gombosi +4
The Voyager spacecraft is now approaching the edge of the solar system. Near the boundary between the solar system and the interstellar medium we find that an unstable ``jet-sheet'…
