  • We present transit photometry of three exoplanets, TrES-4b, HAT-P-3b, and WASP-12b, allowing for refined estimates of the systems' parameters. TrES-4b and WASP-12b were confirmed to be 'bloated' planets, with radii of 1.706 {+-} 0.056R{sub Jup} and 1.736 {+-} 0.092R{sub Jup}, respectively. These planets are too large to be explained with standard models of gas giant planets. In contrast, HAT-P-3b has a radius of 0.827 {+-} 0.055R{sub Jup}, smaller than a pure hydrogen-helium planet and… CONTINUE READING
