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…
HelioFill: Diffusion-Based Model for EUV Reconstruction of the Solar Farside
Firas Ben Ameur, Rayan Dhib, Yahia Battach +4
The loss of STEREO-B in 2014 created a persistent blind spot in Extreme Ultraviolet (EUV) imaging of the solar farside. We present HelioFill, to the authors' knowledge, the first d…
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…
On energy consistency of intermediate states in HLL-type MHD Riemann solvers
Fan Zhang, Andrea Lani, Stefaan Poedts
Approximate Riemann solvers are widely used for solving hyperbolic conservation laws, including those of magnetohydrodynamics (MHD). However, due to the nonlinearity and complexity…
SIP-IFVM: An observation-based magnetohydrodynamic model of coronal mass ejection
Haopeng Wang, Jinhan Guo, Stefaan Poedts +12
Currently, achieving a balance between computational efficiency, accuracy, and numerical stability in CME simulations, particularly in the sub-Alfv{'e}nic coronal region, remains a…
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…
SIP-IFVM: A time-evolving coronal model with an extended magnetic field decomposition strategy
Haopeng Wang, Liping Yang, Stefaan Poedts +20
Time-evolving magnetohydrodynamic (MHD) coronal modeling, driven by a series of time-dependent photospheric magnetograms, represents a new generation of coronal simulations. This a…
