COCONUT: Toward practical time-evolving Sun-to-Earth magnetohydrodynamic modeling
Haopeng Wang, Stefaan Poedts, Andrea Lani +16
Due to computational efficiency and numerical stability limitations, coronal simulations constrained by static magnetograms are typically performed first and then used to drive inn…
MHD modeling of magnetic flux evolution around solar maximum by the coronal model COCONUT
Haopeng Wang, Stefaan Poedts, Andrea Lani +15
In this paper, we simulate the magnetic flux evolution at different heliocentric distances during two solar-maximum Carrington rotations (CRs) using the time-evolving coronal magne…
Data-driven Magnetohydrodynamic Simulation of the Initiation of a Coronal Mass Ejection with Multiple Stages
J. H. Guo, S. Poedts, B. Schmieder +8
Coronal mass ejections (CMEs) are the primary drivers of adverse space-weather events, yet their initiation and onset prediction remain insufficiently understood due to the complex…
Elongation of a Solar Filament and its Three-Dimensional Numerical Reconstruction for Magnetic Structures
Garima Karki, Jinhan Guo, Brigitte Schmieder +4
Quiescent filaments are prominent features of the solar atmosphere, and their evolution reflects the coronal magnetic field's response to photospheric magnetic activity. Here, we r…
COCONUT: A coronal model with an energy decomposition strategy
Haopeng Wang, Stefaan Poedts, Andrea Lani +11
In this paper, we propose an energy decomposition method combined with an HLL Riemann solver that includes an additional dissipation term in the energy equation to improve the nume…
Time-evolving coronal modelling of the solar maximum around the solar storms in May 2024 by COCONUT
Haopeng Wang, Stefaan Poedts, Andrea Lani +8
Time-evolving MHD coronal models deliver more realistic results than traditional quasi-steady-state models. The fully implicit time-evolving coronal model COCONUT performs efficien…
