Rotation of flux ropes in the low corona
Brigitte Schmieder, Anwesha Maharana, Jin Han Guo +2
Eruptions of filaments are defined by different parameters, specially, sigmoid handedness and direction of the eruption, which are important parameters for forecasting the geoeffec…
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…
Flare energetics, CME launch and heliospheric propagation for the May 2024 events, as derived from ensemble MHD modelling
Brigitte Schmieder, Jinhan Guo, Guillaume Aulanier +2
Many questions must be answered before understanding the relationship between the emerging magnetic flux through the solar surface and the extreme geoeffective events. The main ing…
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…
Modelling gyrosynchrotron emission from coronal energetic electrons in a CME flux rope
Edin Husidic, Nicolas Wijsen, Immanuel Christopher Jebaraj +4
Solar flares and coronal mass ejections (CMEs) can accelerate electrons, causing bursts such as type IV emissions in the solar radio continuum. Although radio spectroscopy is a pow…
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…
Data-constrained 3D MHD Simulation of a Spiral Jet Caused by an Unstable Flux Rope Embedded in Fan-spine Configuration
Z. F. Li, J. H. Guo, X. Cheng +5
Spiral jets are impulsive plasma ejections that typically show an apparent rotation motion. Their generation, however, is still nont understood thoroughly. Based on a high-resoluti…
The Birth of a Major Coronal Mass Ejection with Intricate Magnetic Structure from Multiple Active Regions
Jinhan Guo, Y. W. Ni, B. Schmieder +9
Coronal mass ejections (CMEs) are the eruptions of magnetised plasma from the Sun and are considered the main driver of adverse space weather events. Hence, undrstanding its format…
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…
Icarus 3.0: Dynamic Heliosphere Modelling
Tinatin Baratashvili, Beatrice Popescu Braileanu, Fabio Bacchini +2
Space weather predictions are necessary to avoid damage caused by intense geomagnetic storms. Such strong storms are usually caused by a co-rotating interaction region (CIR) passin…
