GIMLI: a toolkit connecting linear and non-linear magnetohydrodynamic regimes
Jordi De Jonghe, Nicolas Brughmans, Rony Keppens
In this work, we present the General Interface for MPI-AMRVAC / Legolas Interconnection (or GIMLI, for short) as a toolkit for in-depth (magneto)hydrodynamic studies combining line…
Streamer slab eigenmode analysis with the Legolas code
Jordi De Jonghe, Daria Sorokina, Tom Van Doorsselaere
Context. Helmet streamers are large ray-like structures extending from the solar corona that thin further away from the solar surface, forming an extended current sheet. These stru…
Thermal instability in coronal loops: linking eigenvalue spectra to time-dependent evolution
Adrian Kelly, Rony Keppens, Jordi De Jonghe
Cool, dense condensations such as coronal rain and prominences suggest that coronal plasma can undergo runaway radiative cooling. Connecting this behaviour to linear thermal modes…
Collisional damping of wave modes in ion-electron plasmas
Joeri De Vadder, Jordi De Jonghe, Rony Keppens
To expand on recent work, we introduce collisional terms in the analysis of the warm ion-electron, two-fluid equations for a homogeneous plasma at rest. Consequently, the plasma is…
Modification of the resistive tearing instability with Joule heating by shear flow
Jordi De Jonghe, Rony Keppens
We investigate the influence of background shear flow on linear resistive tearing instabilities with Joule heating for two compressible plasma slab configurations: a Harris current…
Neural network classification of eigenmodes in the magnetohydrodynamic spectroscopy code Legolas
Jordi De Jonghe, Michał D. Kuczyński
To predict the immediate evolution of a plasma system, one needs to identify the nature of the dominant instability. In this work, a neural network is employed to address a non-bin…
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…
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…
