Abstract
  • Our aim is to perform Non-LTE iron abundance calculations on a sample of Kepler red giants with reliable fundamental atmospheric parameters from asteroseismology, specifically log g, in order to calibrate for unknown atomic collisional effects with neutral hydrogen for which quantum mechanical data does not yet exist. Preliminary results show better mutual agreement between FeI and FeII lines as compared to LTE, as well as less FeI abundance dispersion than that of previous work.
