  1. 1. Examining LUMBA UVES pipeline spectroscopy on giant and sub-giant stars of M67

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Nikolaos Papakonstantinou; [2021]
    Keywords : methods: numerical; stars:abundances; stars: atmospheres; stars: statistics; stars:giants; stars:subgiants; stars: open clusters; stars: M67;

    Abstract : In this work, the efficiency of the LUMBA UVES pipeline for processing of spectroscopic observations is tested by use on 23 high-resolution spectra of the open star cluster M67. An abundance trend discovered by Gavel et al. (2019) concerning iron abundances of giant and sub-giant stars of that cluster is examined. READ MORE
