Modelling Stellar Irradiance III: A predictive model for solar irradiances

Evangelia Deliporanidou, G. Del Zanna

Monthly Notices of the Royal Astronomical Society (2026)

Developed a physically driven semi-empirical model for predicting solar EUV irradiances, using atomic physics and correlations with proxies of activity such as the F30 cm radio flux.

Modelling Stellar Irradiances II: Correlations of solar irradiances with proxies of activity along a cycle

Evangelia Deliporanidou, G. Del Zanna, T. N. Woods, D. Woodraska

Monthly Notices of the Royal Astronomical Society (2025)

Quantified correlations between solar EUV irradiances and multiple proxies of activity, investigating solar-cycle variations and evaluating solar-irradiance observational data from SDO/EVE and SOHO/CDS.

H, He-like recombination spectra VI: quadrupole l-changing collisions

Evangelia Deliporanidou, N. R. Badnell, P. J. Storey, G. Del Zanna, G. J. Ferland

Monthly Notices of the Royal Astronomical Society (2025)

Calculated quadrupole l-changing collision rates for hydrogen- and helium-like ions, improving theoretical recombination spectra used in astrophysical plasma diagnostics.
