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,…
Interaction between a Coronal Mass Ejection and Comet 67P/Churyumov-Gerasimenko
Zhenguang Huang, Gabor Toth, Tamas I. Gombosi +6
The interaction between a Coronal Mass Ejection (CME) and a comet has been observed several times by in-situ observations from the Rosetta Plasma Consortium (RPC), which is designe…
Adjusting the Potential Field Source Surface Height Based on MHD Simulations
Zhenguang Huang, Gabor Toth, Jia Huang +3
A potential field solution is widely used to extrapolate the coronal magnetic field above the Sun's surface to a certain height. This model applies the current-free approximation a…
Solar Wind Driven from GONG Magnetograms in the Last Solar Cycle
Zhenguang Huang, Gabor Toth, Nishtha Sachdeva +1
In a previous study, Huang et al. (2023) used the Alfven Wave Solar atmosphere Model (AWSoM), one of the widely used solar wind models in the community, driven by ADAPT-GONG magnet…
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),…
