Cerium Features in Kilonova Near-infrared Spectra: Implication from a Chemically Peculiar Star

Cerium Features in Kilonova Near-infrared Spectra: Implication from a Chemically Peculiar Star

Observations of the kilonova from the neutron star merger event GW170817 opened a way to study r -process nucleosynthesis directly using neutron star mergers. It is, however, challenging to identify individual elements in kilonova spectra due to a lack of complete atomic data, in particular at near-...
