WASP-122b in the T_eff – |λ| plane compared to the rest of the confirmed planets with an obliquity measurement (top). The colors indicate the planetary radius. WASP-122b is marked with a “star” symbol. The sample of planets with an obliquity measurement was extracted from the TEPCat catalog (Southworth 2011). In the case of planets with more than one measurement, we plot the mean of those values, with the error bar indicating the span between the maximum and minimum literature values. Bottom panel: Histogram of number of planets with λ > 30 deg and λ < 30 deg, depending on the T_eff of their main star. In both panels, vertical grey dashed lines indicate the T_eff = 6250 K.
