Abstract:
We present the discovery of two transiting exoplanets. HAT-P-28b
orbits a V=13.03 G3 dwarf star with a period P=3.2572 days and has a
mass of 0.63±0.04MJ and a radius of 1.21+0.11-0.08RJ
yielding a mean density of 0.44±0.09g/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+0.08-0.04MJ and a radius of 1.11+0.14-0.08RJ yielding
a mean density of 0.71±0.18g/cm3. We discuss the properties of
these planets in the context of other known transiting planets
Description:
In-transit photometric observations of HAT-P-28 and HAT-P-29 were
obtained with the KeplerCam CCD camera on the FLWO 1.2m telescope and
with the 2.0m Faulkes Telescope North (FTN) at Haleakala Observatory
in Hawaii, in 2010 Sep 3 and 6 (KeplerCam) and 2010 Oct 2 (FTN) for
HAT-P-28 and in 2011 Jan 1 and 24 (KeplerCam) for HAT-P-29.

Note (1): The out-of-transit level has been subtracted. These magnitudes have
been subjected to the External Parameter Decorrelation (EPD)
technique and Trend Filtering Algorithm (TFA) procedures
(see Bakos et al. 2010, Cat. J/ApJ/710/1724), carried out
simultaneously with the transit fit.
Note (2): Without application of the EPD and TFA procedures.
