[X/H] for neutron-capture elements compared to age. Only stars with age uncertainties less than 3 Gyr are plotted. The vertical dotted line at 8 Gyr indicates an approximate age separation between thin and thick disks. Blue dots represent thin disk stars with [Ti/Fe] < 0.2, while red dots indicate thick disk stars identified with [Ti/Fe] > 0.2. The average error on the abundance ratio is indicated in black.
