Insolation and orbital period vs. planet size. TOI 4342 b and TOI 4342 c are shown in cyan over occurrence contours for host stars with M * < 0.97 M from Fulton & Petigura (2018). M-dwarf TOIs as of 2022 July 7 are plotted as well, with multiplanet system planets highlighted in magenta. TOI 4342 b and TOI 4342 c both lie in the upper end of the radius valley.
