Insolation flux and planet radius for all extrasolar planets with known radius, T_eff, and semi-major axis. Data taken from the The Extrasolar Planet Encyclopedia. The two hot Jupiters found in this work are marked as filled circles (K2-34 in red and K2-30 in blue). The expected radius-insolation flux dependencies according to Weiss et al. (2013) are shown as dashed red (K2-34) and dash-dotted blue (K2-30) lines.
