simesh: A Python Framework for Quantitative Analysis of Native AMR Data from MPI-AMRVAC
Hao Wu, Jinhan Guo, Rony Keppens +1
Adaptive mesh refinement (AMR) is widely used in large-scale astrophysical simulations, but the resulting multilevel data are challenging to analyze quantitatively. We present sime…
Flares and flux ropes: an entangled story
Rony Keppens, Yang Guo, Wenzhi Ruan
Solar flares serve as standard candles for all magnetic-reconnection-based energy releases, and their consequences into the heliosphere can be modeled from first principles. This r…
Multi-thermal Structure of Solar Jets based on Combined EUV and Ha Observations
Lei Huang, Yang Guo, Zining Ren +1
This study investigates the multi-thermal structure of solar jets by combining extreme ultra-violet (EUV) and Ha observations, addressing whether cool and hot components originate…
Multiple Extreme Ultraviolet Peaks Attributed to Three-dimensional Magnetic Reconnection in a Long-duration Solar Flare
Shihan Li, Jinhan Guo, Wensi Wang +5
Solar flares are a major driver of hazardous space weather, whose intense electromagnetic emissions and energetic particles can significantly disturb the near-Earth space environme…
Rotation of a Solar Jet Driven by Plasma Flow along Helical Magnetic Fields in an Active Region
Lei Huang, Yang Guo, Zhen Li +2
Solar jets, collimated plasma ejections driven by magnetic reconnection, play a vital role in energy transport and coronal heating. While rotational motions in jets are often attri…
Particle Acceleration and Transport in the Large-scale Current Sheet under an Erupting Magnetic Flux Rope
Hao Wu, Yang Guo, Rony Keppens +4
We investigate the acceleration and transport of electrons in the highly fine-structured current sheet that develops during magnetic flux rope (MFR) eruptions. Our work combines ul…
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…
Data-constrained Magnetohydrodynamic Simulation of a Filament Eruption in a Decaying Active Region 13079 on a Global Scale
Yihua Li, Yang Guo, Jinhan Guo +3
Filaments are special plasma phenomena embedded in the solar atmosphere, characterized by unique thermodynamic properties and magnetic structures. Magnetohydrodynamic (MHD) simulat…
Rotation and Confined Eruption of a Double Flux-Rope System
Xiaomeng Zhang, Jinhan Guo, Yang Guo +2
We perform a data-constrained simulation with the zero- assumption to study the mechanisms of strong rotation and failed eruption of a filament in active region 11474 on 2012 Ma…
A Method for Determining the Locations and Configurations of Magnetic Reconnection within 3D Turbulent Plasmas
Yulei Wang, Xin Cheng, Yang Guo +2
Context. Three-dimensional (3D) reconnection is an important mechanism for efficiently releasing energy during astrophysical eruptive events, which is difficult to be quantitativel…
Data-constrained Magnetohydrodynamic Simulation of an Intermediate Solar Filament Eruption
Yang Guo, Jinhan Guo, Yiwei Ni +5
Solar eruptive activities could occur in weak magnetic field environments and over large spatial scales, especially relevant to eruptions involving intermediate or quiescent solar…
Formation and Characteristics of Filament Threads in Double-Dipped Magnetic Flux Tubes
Jinhan Guo, Yuhao Zhou, Yang Guo +3
As one of the main formation mechanisms of solar filament formation, the chromospheric evaporation-coronal condensation model has been confirmed by numerical simulations to explain…
Transition from circular-ribbon to parallel-ribbon flares associated with a bifurcated magnetic flux rope
Z. Zhong, Y. Guo, M. D. Ding +2
Magnetic flux ropes play a key role in triggering solar flares in the solar atmosphere. In this paper, we investigate the evolution of active region NOAA 12268 within 36 hours from…
