Li abundance as a function of [Fe/H] with nova as a sole stellar source and with different mass fractions of Li in the nova ejecta. Our ‘best-fit’ value (red dashed line) is slightly higher than the mean value of the observational analysis of Molaro et al. (2022) (red solid line), and the pinkish shaded area corresponds to the dispersion of X_Li around that mean value. The theoretical nova Li yields of José & Hernanz (1998) and Starrfield et al. (2024) are also used (purple and cyan curves, respectively). The five-pointed stars show the abundance of the open clusters, while the underlying number density plot represents the GALAH sample. The solar symbol indicates the meteoritic value.
