Description

AT2017gfo is the first clearly detected kilonova, with comprehensive photometry and spectroscopy in the optical and NIR. I discuss this unique dataset in the context of previously published models and show fitting results using newly developed ones. I discuss inferred constraints on ejecta mass and composition in relation to simulations of neutron star mergers and theories for the origin of the r-process elements.
