Estimate for chemical abundances of accreted gas. This is based on condensation temperatures of elements and the most depleted observed post-AGB stars. The abundances displayed are with respect to the initial composition of the star. Elements with higher condensation temperatures (Tcond) have lower accretion abundances. We use this chemical composition for the accreted gas in our MESA models.
