Example data from a 1.5-hour GHOST SV observation of 2MASSJ1424, an extremely metal-poor star with enhancements in r-process elements. The panels highlight atomic and molecular absorption features used for the determination of atmospheric parameters (Teff, logg, and [Fe/H]) and chemical abundances. These data will allow for a more complete chemical inventory of this star’s atmosphere and a chemodynamical analysis that can further constrain its progenitor.
