Modelling Stellar Irradiances II: Correlations of solar irradiances with proxies of activity along a cycle
E. Deliporanidou, G. Del Zanna, T. N. Woods +1
There is a pressing need to model X-ray Ultra-Violet (XUV: 1-30 nm) stellar irradiances, given the scarcity of current measurements. One of the measurable effects of a stellar cycl…

H, He-like recombination spectra VI: Quadrupole -changing collisions
E. Deliporanidou, N. R. Badnell, P. J. Storey +2
We have developed a simple analytic formula that well describes quadrupole -changing collisions of the form , as confirmed by comparison with numerical quant…

Modelling Stellar Irradiances I: the transition regions of FGKM stars
Evangelia Deliporanidou, Giulio Del Zanna
We employed advanced ionisation equilibrium models that we developed in Dufresne et. al. (2024), which include charge transfer and density effects, to model UV stellar irradiances…
