Caption: Figure 1.
Orbital period vs. planet radius for transiting planets. Gray points are from the TEPCat catalog (J. Southworth 2011) as of 2025 November. Colored points are those for which the stellar obliquity has been measured, with five-pointed stars highlighting TOI-181 b and TOI-883 b. Dashed blue lines indicate the boundaries of the Neptune desert, ridge, and savanna as defined by A. Castro-González et al. (2024). The background color conveys the density of data points.
