Lanthanide Features in Near-infrared Spectra of Kilonovae
Nanae Domoto, Masaomi Tanaka, Daiji Kato +3
The observations of GW170817/AT2017gfo have provided us with evidence that binary neutron star mergers are sites of -process nucleosynthesis. However, the observed signatures in…

Opacity of the highly ionized lanthanides and the effect on the early kilonova
Smaranika Banerjee, Masaomi Tanaka, Daiji Kato +3
We investigate the effect of the presence of lanthanides (Z = 57- 71) on the kilonova at t~hours after the neutron star merger for the first time. For this purpose, we calculate th…
