Histogram of stellar metallicity (top) in the GALAH catalogue with solar metallicity for comparison (Asplund et al. 2009), and 50% condensation temperature of various elements as a function of host stellar metallicity (bottom). Each column of condensation temperatures is calculated from a condensation sequence with solar abundances scaled to the corresponding metallicity. Condensation temperatures are shown relative to the simulation with unsealed solar abundances (Table 1).
