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…

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…
