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 RJ yielding a mean density of 0.44 ± 0.09 g cm-3 . 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 1.1+0.14 -0.08 RJ yielding a mean density of 0.71 ± 0.18 g cm-3 . We discuss the properties of these planets in the context of other known transiting planets. [ABSTRACT FROM AUTHOR]- Published
