Relative abundances of Li/H in nova explosions. The shaded area shows the range of observed values and the red horizontal line is the average value, as reported in Molaro et al. (2022). Curves represent the highest values found in the calculations of Starrfield et al. (2024, in red), Rukeya et al. (2017, in green) and Gao et al. (2024, in blue), in explosions of CO and ONe white dwarfs of various masses. The results of José et al. (2020) are considerably below the scale of the figure.
