NLTE calculations indicate strontium is required to explain the onset of the 1μm feature at early times in AT2017gfo, while helium can dominate at later epochs with plausible masses.

Detection of GW190814 from the coalescence of a 23 solar-mass black hole and a 2.6 solar-mass compact object, the most unequal-mass binary yet observed with gravitational waves.
Non-LTE models for He and Sr in kilonova ejecta show that ~1% He or 1-10% Sr can reproduce the 1μm absorption feature in AT2017gfo, implying low-Ye, low-entropy r-process conditions.
Observational analysis of EMP stars including a new r-process enhanced star G256353 whose heavy-element pattern matches scaled solar and neutron-star-merger predictions, supporting r-process universality.
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.
Magnetorotational r-process best explains lighter elements and CEJSN explains the third peak based on scatter and iron correlations in early metal-poor stars.
BILBY is validated on simulated compact binary signals and reproduces the eleven GWTC-1 results with configuration and output files provided for reproduction.
