Numerical simulations of waves and turbulence in coronal loops: observables and spectra
Fabio Feraco, Francesco Pucci, Claudio Meringolo +11
We investigate numerically the time evolution of velocity and magnetic field fluctuations in a coronal loop, focusing on the dynamics due to both phase mixing and turbulent cascade…
On the cool nature of coronal nanojets
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +5
Reconnection-driven nanoflares are widely considered a leading mechanism for coronal-loop heating, but their direct fingerprints in the tenuous coronal plasma remain elusive. The r…
3D MHD simulations of coronal loops heated via magnetic braiding II. Automatic detection of reconnection outflows and statistical analysis of their properties
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +5
Recent observations of fast and bursty ``nanojets'' suggest novel diagnostics of nanoflare heating in the solar corona. The aim of this work is to investigate the presence and prop…
3D MHD simulations of coronal loops heated via magnetic braiding I. Continuous driving
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +13
The nature and detailed properties of the heating of the million-degree solar corona are important issues that are still largely unresolved. Nanoflare heating might be dominant in…
Coronal energy release by MHD avalanches III. Identification of a reconnection outflow from a nanoflare
G. Cozzo, P. Pagano, F. Reale +5
Outflows perpendicular to the guide field are believed to be a possible signature of magnetic reconnection in the solar corona and specifically a way to detect the occurrence of ub…
