We present numerical simulations with MPI-AMRVAC of solar prominences, embedded in a realistically stratified solar atmosphere. The prominences show vigorous nonlinear magnetoconvective motions, as their density contrast triggers Rayleigh-Taylor/interchange instability dynamics. We present virtual SDO/AIA views, and contrast our findings with observational ones.

We extend our earlier multidimensional, magnetohydrodynamic simulations of coronal rain occurring in magnetic arcades with higher resolution, grid-adaptive computations covering a much longer ($>6$ hour) timespan.
We quantify how in-situ forming blob-like condensations grow along and across field lines and show that rain showers can occur in limit cycles, here demonstrated for the first time...

Coronal rain phenomena are simulated in 3D setups in a magnetic configuration of a quadrupolar arcade system. A magnetohydrodynamic simulation is presented including three gain-loss terms, anisotropic thermal conduction, optically thin radiative losses, and parametrised heating to construct a realistic arcade configuration from chromospheric to coronal heights. Evaporated plasma from...

UTR-2 (Kharkiv, Ukraine) and URAN-2 (Poltava, Ukraine) are world-largest radio telescopes at decametric wavelengths. High sensitivity and time resolution of these telescopes allowed revealing many new features of the coronal radio emission. We discuss narrow-band coronal radio bursts at 23-35 MHz with frequency drift rates ~ 110 kHz. These bursts appear between type III and type II bursts and...
