Scatterplots of the nitrogen isotopic ratio as a function of Tdust (left panel) and CO depletion factor (right panel). Red stars represent protostellar cores from this work, whilst the blue dots represent the prestellar source analysed by Redaelli et al. (2018). Tdust and fD values for YSOs are taken from Emprechtinger et al. (2009). For prestellar objects, the Tdust values are taken from Chacón-Tanarro et al. (2019) and Redaelli et al. (2018); the values of fD are taken from Crapsi et al. (2005).
