Description
Kilonovae are expected to enter the nebular phase on a time scales of weeks. In the nebular phase, the kilonova spectra are considered to be composed of emission lines of r-process elements. Observing the nebular spectra may offer us unique opportunities to identify elements synthesized in neutron star merger ejecta. I will introduce some important concepts in the nebular modelings. Then the possible identifications of strong emission lines in AT 2017gfo as well as in the late-time JWST spectrum of GRB 230307A.
