Fig. 3

Radiation pressure to gravitational force ratio β as a function of grain radius s for KIC 1255b. Different colours correspond to the materials listed in Table 2. Uncertainties (due to uncertainties in stellar parameters) are indicated by the error bar in the bottom left. The same figure for KOI-2700b is qualitatively the same, but the β values are lower by a factor of about 1.5.
