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…
