Abundances, Analysis and Plotting

(Pre-Course Assignment)

Analyze and plot abundances:

  1. Grab the solar system abundances and plot them
    • Cite the data source (Anders & Grevesse, Lodders, Asplund, etc)
    • Vs mass number (A)
    • Vs atomic number (Z)
  2. Grab stellar abundances from the SAGA Database for a handful of stars
    • Plot abundances $[A/B]= \log_{10}(A/B)_{star} - \log_{10}(A/B)_\odot$
      • [Ca/H], [Ge/H], [Zr/H], [Sr/H], [Ba/H], [Eu/H], [Os/H], [Pt/H], [Pb/H] vs [Fe/H]
        • Are these elements correlated with metallicity?
        • Do they have the same correlation?
      • [Ca/Fe], [Ge/Fe], [Zr/Fe], [Sr/Fe], [Ba/Fe], [Os/Fe], [Pt/Fe], [Pb/Fe] vs [Eu/Fe]
        • Are these elements correlated with Eu?
