Fig. 1

Mass vs. incident flux, expressed in units of flux received at Earth, for transiting exoplanets with V < 16 and masses determined to <20% precision (gray circles). The size of the symbols is proportional to the planet bulk density. WASP-49b is shown in red; HD 189733b, HD 209458b, and WASP-8b (see Sect. 4.3) are in blue, green, and black, respectively.
