Comparing HD 332231 to the literature. Left: projected obliquities versus orbital separations Right: projected obliquities versus orbital eccentricities. We only include planets more massive than 0.2 M_jupiter. In the right panel, we further only plot planets on large (a/R > 15) orbits and with <σ_ecc < 0.1. HD 332231 is marked by a red star; the system belongs to the class of systems with low orbital misalignment, and low orbital eccentricity.
