Astrophysics on GPUs: introducing AGILE 1.0
Oliver Porth, Adrian Kelly, Olaf Willocx +10
We present AGILE, a GPU-enabled adaptive mesh refinement (AMR) framework for the solution of (near-) conservation laws which occur in astro- and solar-physical applications. AGILE…
foap4: Adaptive mesh refinement with OpenACC, MPI, and p4est
Jannis Teunissen, Héctor R. Olivares Sánchez, Jesse Vos +10
GPUs and other accelerators are increasingly used for scientific computing. In the future, we want to add GPU support to parallel adaptive mesh refinement (AMR) codes written in Fo…
On the dynamics, thermodynamics and fine structure of virtual erupting filaments
Dion Donné, Yuhao Zhou, Hebe Cremades +1
It is not fully understood why some solar filaments erupt while others do not. Those that do typically undergo a slow rise followed by an acceleration phase, though this transition…
The Formation of Solar Prominences: Plasma Origin and Mechanisms
Yuhao Zhou
Solar prominences, or solar filaments, are cool and dense plasma structures in the hot solar corona, whose formation mechanisms have remained a fundamental challenge in solar physi…
Modeling multiphase plasma in the corona: prominences and rain
Rony Keppens, Yuhao Zhou, Chun Xia
We review major achievements in our understanding of multiphase coronal plasma, where cool-dense and hot-tenuous matter coexists, brought about by advances in modeling and theory,…
Response of the solar atmosphere to flux emergence: With emergence-driven prominence formation
Xiaohong Li, Yuhao Zhou, Rony Keppens
Flux emergence is crucial for the formation of solar active regions and triggering of various eruptions. However, the detailed mechanisms by which flux emergence drives these erupt…
Frozen-field Modeling of Coronal Condensations with MPI-AMRVAC II: Optimization and application in three-dimensional models
Yuhao Zhou, Xiaohong Li, Jack M. Jenkins +2
The frozen-field hydrodynamic (ffHD) model is a simplification of the full magnetohydrodynamical (MHD) equations under the assumption of a rigid magnetic field, which significantly…
Frozen-field Modeling of Coronal Condensations with MPI-AMRVAC I: Demonstration in two-dimensional models
Yuhao Zhou, Xiaohong Li, Rony Keppens
Large-scale coronal plasma evolutions can be adequately described by magnetohydrodynamics (MHD) equations. However, full multi-dimensional MHD simulations require substantial compu…
Winking filaments due to cyclic evaporation-condensation
Yuhao Zhou, Xiaohong Li, Jie Hong +1
Observations have shown that some filaments appear and disappear in the H line wing images periodically. There have been no attempts to model these "winking filaments" thus far.…
Transverse vertical oscillations during the contraction and expansion of coronal loops
Qingmin Zhang, Yuhao Zhou, Chuan Li +5
In this paper, we carry out a detailed analysis of the M1.6 class eruptive flare occurring in NOAA active region 13078 on 2022 August 19. The flare is associated with a fast corona…
Multi-thermal jet formation triggered by flux emergence
Xiaohong Li, Rony Keppens, Yuhao Zhou
Flux emergence is responsible for various solar eruptions. Combining observation and simulations, we investigate the influence of flux emergence at one footpoint of an arcade on co…
MPI-AMRVAC 3.0: updates to an open-source simulation framework
Rony Keppens, Beatrice Popescu Braileanu, Yuhao Zhou +5
Computational astrophysics routinely combines grid-adaptive capabilities with modern shock-capturing, high resolution spatio-temporal schemes on multi-dimensional hydro- and magnet…
Rapid Rotation of an Erupting Prominence and the Associated Coronal Mass Ejection on 13 May 2013
Yuhao Zhou, Haisheng Ji, Qingmin Zhang
In this paper, we report the multiwavelength observations of an erupting prominence and the associated CME on 13 May 2013. The event occurs behind the western limb in the field of…
Coronal rain in randomly heated arcades
Xiaohong Li, Rony Keppens, Yuhao Zhou
Adopting the MPI-AMRVAC code, we present a 2.5-dimensional magnetohydrodynamic (MHD) simulation, which includes thermal conduction and radiative cooling, to investigate the formati…
When hot meets cold: post-flare coronal rain
Wenzhi Ruan, Yuhao Zhou, Rony Keppens
Most solar flares demonstrate a prolonged, hourlong post-flare (or gradual) phase, characterized by arcade-like, post-flare loops (PFLs) visible in many extreme ultraviolet (EUV) p…
Simulations of solar filament fine structures and their counterstreaming flows
Y. H. Zhou, P. F. Chen, J. Hong +1
Solar filaments, also called solar prominences when appearing above the solar limb, are cold, dense materials suspended in the hot tenuous solar corona, consisting of numerous long…
Transition region adaptive conduction (TRAC) in multidimensional magnetohydrodynamic simulations
Yu-Hao Zhou, Wen-Zhi Ruan, Chun Xia +1
In solar physics, a severe numerical challenge for modern simulations is properly representing a transition region between the million-degree hot corona and a much cooler plasma of…
Modeling the IRIS Lines During a Flare. I. The Blue-Wing Enhancement in the Mg II k Line
Jie Hong, Ying Li, M. D. Ding +1
The IRIS Mg II k line serves as a very good tool to diagnose the heating processes in solar flares. Recent studies have shown that apart from the usual red asymmetries which are in…
