Relationship between [Ce/Fe] and [Fe/H], age, and R_gc (left) and [Ce/H] as a function of [Fe/H], age, and R_gc (right). The black hexagons are the OCs studied in our previous paper, Seshashayana et al. (2024). Data for field stars taken from Ryde et al. (2020) are shown as light blue dots. The clusters taken from Myers et al. (2022) are shown as light gray squares. The slopes were obtained via a fit to all strictly similarly analyzed OCs from this and our previous work, excluding the outlier NGC 6791 (see Seshashayana et al. 2024, for a discussion).
