The Prospector-derived star formation histories (SFHs) of the 12 GRB-KN host galaxies in our sample. This sample has a diverse array of SFHs and recent star formation bursts, hinting that some events might be more capable of enriching their environmental star-forming gas with r-process elements than others.
