unveiling systematic biases in the 1d lte excitation-ionization balance of fe for fgk stars: A novel approach to determination of stellar parameters

Ruchti, Gregory R.; Bergemann, Maria; Serenelli, Aldo; Casagrande, Luca; Lind, Karin

Description

We present a comprehensive analysis of different techniques available for the spectroscopic analysis of FGK stars and provide a recommended methodology which efficiently estimates accurate stellar atmospheric parameters for large samples of stars. Our analysis includes a simultaneous equivalent width analysis of Fe I and Fe II spectral lines, and for the first time, utilizes on-the-fly non-local thermodynamic equilibrium (NLTE) corrections of individual Fe I lines. We further investigate...[Show more]
