Eigenmode initialisation of 2D (magneto)hydrodynamic simulations
Jordi De Jonghe, Alexander J. B. Russell
The early evolution of unstable hydrodynamic and magnetohydrodynamic equilibria is often governed by a few dominant linear eigenmodes. We investigate whether initialising a simulat…

The hydrodynamic thermal continuum, with applications to stratified atmospheres and 1D coronal loop models
Rony Keppens, Jordi De Jonghe, Adrian Kelly +2
Using both analytical and numerical means, we demonstrate that linear stability analysis of a hydrodynamic stratified atmosphere or a 1D coronal loop model in non-adiabatic setting…

The coupled tearing-thermal instability in coronal current sheets from the linear to the non-linear stage
Jordi De Jonghe, Samrat Sen
In the solar corona, magnetically sheared structures are unstable to both tearing and thermal instabilities in a coupled fashion. However, how the choice of linear perturbation mod…
