finding binding
boundEarly optical/ultraviolet absorption features in AT2017gfo (particularly strontium, yttrium, zirconium lines) reveal r-process nucleosynthesis in the merger ejecta, though heavier r-process elements like gold and platinum cannot be unambiguously identified due to high ejecta velocities (~0.1–0.2c).
