Frequency distribution of parent-star metallicity for transiting exoplanets with 10M_⊕<M_p<100M_⊕ (Vissapragada & Behmard 2025). The histograms are shown with a 0.1 bin and for the three different populations identified by Castro-González et al. (2024a). ‘Desert’ refers to Neptune planets with orbital periods P_orb< 3.2 days; ‘Ridge’ to those with 3.2 days < P_orb < 5.7 days; and ‘Savanna’ to those with 5.7 days < P_orb<100 days. Data were obtained on June 6, 2025 from TEP-Cat. The dashed vertical line marks the metallicity measured for the parent star of TOI-5795 b.
