[C/Fe], [N/Fe], and [O/Fe] abundances and C/O and N/O ratios as functions of [Fe/H] for observed dwarfs (left panel) and giants (right panel). Thin disc planet-hosting stars are represented by green circles, while pink circles indicate stars from the thick disc. Circles filled with both colours represent “in between stars” to thin and thick discs. The (coloured) diamond symbols represent the planets-hosts from Tautvaišienė et al. (2022). The comparison sample results are taken from Stonkutė et al. (2020); Tautvaišienė et al. (2022) and indicated by empty grey squares (thin disc) and triangles (thick disc).
