Abstract (from CDS):

We present the discovery of two transiting exoplanets. HAT-P-28b orbits a V = 13.03 G3 dwarf star with a period P = 3.2572 days and has a mass of 0.63±0.04 M_J and a radius of 1.21^+0.11_- 0.08_RJ_yielding a mean density of 0.44±0.09 g/cm3. HAT-P-29b orbits a V = 11.90 F8 dwarf star with a period P = 5.7232 days and has a mass of 0.78^+0.08_- 0.04_MJ_ and a radius of 1.11^+0.14_- 0.08_RJ_ yielding a mean density of 0.71 ±0.18 g/cm3. We discuss the properties of these planets in the context of other known transiting planets.
