A one-zone model shows that observed [Y/Eu] and [Sr/Eu] trends require a prompt first-peak channel, delayed BNS mergers dominating Eu, and delayed AGB s-process with t_min > 0.3 Gyr.
A phenomenological nonequilibrium freeze-out model with Lagrange parameters accounts for both the universal heavy r-process abundance pattern in stars and its observed variations.
New abundance measurements confirm two stars as r-II and one as borderline r-I, with r-process material older than 10 Gyr and possible links to the Thamnos structure.
