Diagnostics for the solar chromosphere using neutral carbon Rydberg lines
R. P. Dufresne, C. M. O. Osborne, G. Del Zanna
Diagnostics for the solar chromosphere are relatively few compared to other parts of the atmosphere. Despite this, hundreds of Rydberg lines emitted by neutrals in this region have…
Improving the atomic modelling for solar UV radiative transfer calculations
R. P. Dufresne, G. Del Zanna, C. M. J. Osborne
Radiative transfer calculations have been produced over the years for many lines and continua in the UV wavelength range of solar and cool stellar atmospheres for a variety of cond…
Satellite lines from autoionizing states of Fe XVI and the problems with the X-ray Fe XVII lines
G. Del Zanna, N. R. Badnell, P. J. Storey
We present new calculations of atomic data needed to model autoionizing states of Fe XVI. We compare the state energies, radiative and excitation data with a sample of results from…
Non-thermal distributions and energy transport in the solar flares
Sarah Matthews, Guilio del Zanna, Ariadna Calcines +9
Determining the energy transport mechanisms in flares remains a central goal in solar flares physics that is still not adequately answered by the 'standard flare model'. In particu…
