Determining iron abundances in cool stars: The role of hydrogen collisions

Activity Leader:  Dr. Rana Ezzeddine, Postdoctoral Associate

Determination of high precision abundances is an important goal of all spectroscopic studies. Accurate modelling of stellar spectra is therefore essential to determine these abundances and stellar parameters. I will explain in this talk the non-Local Thermodynamic Equilibrium (non-LTE) approach to modelling stellar spectra of cool stars, highlighting the important role that Hydrogen collisions play.
