Legolas 2.0: Improvements and extensions to an MHD spectroscopic framework
Niels Claes, Rony Keppens
We report on recent extensions and improvements to the Legolas code, which is an open-source, finite element-based numerical framework to solve the linearised (magneto)hydrodynamic…
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…
The effect of linear background rotational flows on magnetoacoustic modes of a photospheric magnetic flux tube
Samuel Skirvin, Viktor Fedun, Suzana Silva +4
Magnetoacoustic waves in solar magnetic flux tubes may be affected by the presence of background rotational flows. Here, we investigate the behaviour of and modes o…
Legolas: magnetohydrodynamic spectroscopy with viscosity and Hall current
Jordi De Jonghe, Niels Claes, Rony Keppens
Many linear stability aspects in plasmas are heavily influenced by non-ideal effects beyond the basic ideal magnetohydrodynamics (MHD) description. Here, the extension of the moder…
Magnetohydrodynamic spectroscopy of a non-adiabatic solar atmosphere
Niels Claes, Rony Keppens
The quantification of all possible waves and instabilities in a given system is of paramount importance, and knowledge of the full magnetohydrodynamic (MHD) spectrum allows one to…
Legolas: a modern tool for magnetohydrodynamic spectroscopy
Niels Claes, Jordi De Jonghe, Rony Keppens
Magnetohydrodynamic (MHD) spectroscopy is central to many astrophysical disciplines, ranging from helio- to asteroseismology, over solar coronal (loop) seismology, to the study of…
Thermal instabilities: Fragmentation and field misalignment of filament fine structure
Niels Claes, Rony Keppens, Chun Xia
Prominences show a surprising amount of fine structure and it is widely believed that their threads, as seen in H observations, provide indirect information concerning magnetic…
