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…
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…
Total solar eclipse 2024 modelling with COCONUT
Tinatin Baratashvili, Haopeng Wang, Daria Sorokina +2
Coronal modelling is crucial for a better understanding of solar and helio-physics. Due to the strong brightness of the Sun and the lack of white light observations of the solar at…
Investigating the impact of the dynamic solar wind on the propagation of a coronal mass ejection with two models and multi-spacecraft measurements
Tinatin Baratashvili, Emma Davies, Eva Weiler +3
Coronal mass ejections (CMEs) are the main drivers of disturbances in the solar heliosphere because they propagate and interact with the magnetic field of the solar wind. It is cru…
