Radius of all discovered planets around F-, G-, and K-type stars (gray dots) and M-type stars (blue dots) with planetary mass and radius error bars of 30% or smaller, plotted as a function of planetary insolation (left panel) and orbital period (right panel). These data were extracted from the NASA Exoplanetary Archive. The two transiting planets of the TOI-1238 system are marked with a red star symbol. In the right panel, the dashed gray line indicates the radius valley for planets around solar-type stars, whereas the dashed blue line shows the location of the radius valley of planetary systems with M-type parent stars.
