The non-LTE copper abundance of the Sun

I accomplished my thesis work at Stockholm University with doctor Karin Lind. The aim of my thesis was to assemble a new model atom for copper (Cu), using the recently published atomic data, such as energy levels, bound-bound radiative transitions, photo-ionization cross sections, electron collisions and hydrogen collisions. Fine structure and Cu's isotopes were also taken into account. Once I completed my atomic model, I build a synthetic spectrum of Cu lines for the Sun. The spectrum was created using Balder, a radiative transfer code able to perform statistical equilibrium equations' calculations in non-local thermodynamic equilibrium conditions. In the end, I compared the synthetic spectrum with the data for our Star in order to infer the Copper abundance of the Sun.
