Measurements of the sky-projected obliquity λ (left) and the true three-dimensional obliquity ψ (right) for exoplanetary systems as a function of host star effective temperature. Planets with masses less than that of Saturn are colored in blue, while planets more massive than Saturn are shown in gray. Our measurements for TOI-2364are indicated with an orange star. The possible bimodality of the orbits of planets less massive than Saturn around cool stars is more clearly revealed in the true obliquity distribution than in the sky-projected distribution. Measurements were compiled from S. H. Albrecht et al. (2022), E. Knudstrup et al. (2024), and the TEPCat catalog (J. Southworth 2011), as of 2025 February 28.
