Abstract

We present the discovery of two transiting exoplanets. HAT-P-28b orbits a V = 13.03 G3 dwarf star with a period P = 3.2572days and has a mass of 0.63 0.04M_J and a radius of 1.21^+0.11_-0.08R _J yielding a mean density of 0.44 0.09g cm^-3. HAT-P-29b orbits a V = 11.90 F8 dwarf star with a period P = 5.7232days and has a mass of 0.78^+0.08_{- 0.04}M_J and a radius of 1.11 ^+0.14_{- 0.08}R_J yielding a mean density of 0.71 ± 0.18g cm^-3. We discuss the properties of these planets in the context of other known transiting planets.
