3. 2. Measuring copper abundances in the Galactic Bulge

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Nikolei Höglinger; [2024]
   Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

   Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.
