[La/Fe] as a function of [Eu/Fe], The figure includes CEMP-s stars, CEMP-rs stars, and r-process-enriched stars from Masseron et al. (2010) and Karinkuzhi et al. (2021 a) as well as the Ba stars of Roriz et al. (2021). The dashed green line corresponds to abundance-ratio scaling with a pure solar r-process (Goriely 1999), whereas the continuous blue line corresponds to s-process nucleosynthesis abundance ratio scaling with the predictions from the fifth pulse of a 1.5 M_⊙ star at [Fe/H] = −1.
