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…
Evidence for anisotropic non-Maxwellian velocity distributions in the solar transition region
Paola Testa, Bart De Pontieu, Kyuhyoun Cho +2
Spectroscopic observations of the solar transition region have long shown excess line broadening and non-Gaussian profiles, but their spatial distribution and prevalence are not we…
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…
The connection between solar coronal abundances and the underlying lower atmospheric properties
Paola Testa, Juan Martinez-Sykora, Bart De Pontieu +4
Elemental abundances in the solar corona and solar wind are often observed to differ from those in the solar photosphere, most commonly showing an enhancement of low first ionizati…
Multi-fluid multi-species models for inverse FIP-effect
Juan Martínez-Sykora, Paola Testa, Deborah Baker +1
The inverse First Ionization Potential (FIP) effect is rarely observed in the solar atmosphere, and this anomaly poses a challenging problem in understanding physical processes dri…
Solar Flare Ion Temperatures
Alexander J. B. Russell, Vanessa Polito, Paola Testa +2
This paper proposes that the ion temperature is several times the local electron temperature in the hot onset phase and at the above-the-loop region of solar flares. The paper cons…
