Magnetohydrodynamic coronal modelling with high-fidelity magnetograms
Haopeng Wang, Stefaan Poedts, Wensi Wang +16
To resolve coronal structures in detail, it is essential to constrain the coronal model using high-fidelity magnetograms with minimal smoothing. In this paper, we improve the numer…
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…
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…
