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…

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…
