1. Collisional broadening by hydrogenfor stellar spectroscopy : extension towards high-lying states
University essay from Uppsala universitet/Teoretisk astrofysikAbstract : The object of this thesis is to extend the current tables for two useful quantities when calculatingcollisional broadening, the cross-section of interaction and the velocity parameter.These quantities, which have hitherto been tabulated for lower states, have now been calculatedfor higher lying states and are used in the ABO - model for spectral line broadening.

2. Broadening of spectral lines in the Gaia-ESO survey
University essay from Uppsala universitet/Teoretisk fysikAbstract : Analyzing stellar spectra plays a big role in understanding the evolution of our galaxy. Having good data for spectral line properties is very important when analyzing these spectra. One part of the Gaia-ESO public spectroscopic survey (GES) is to gather data for spectral line properties from stellar spectra. READ MORE
