More complete lanthanide line data in radiative transfer modeling requires a lanthanide mass fraction of only 2.5e-3 to match the observed spectrum of AT 2017gfo, twenty times below prior claims.
Optimization of dielectronic recombination rates for U II-IV using AUTOSTRUCTURE, benchmarked on Nd III, for implementation in kilonova radiative transfer with SUMO.
Magnetorotational r-process best explains lighter elements and CEJSN explains the third peak based on scatter and iron correlations in early metal-poor stars.
