Abstract:
We report the discovery of three new transiting extrasolar planets
orbiting moderately bright (V=11.1, 11.7, and 12.4) F stars. The
planets HAT-P-39b through HAT-P-41b have periods of P=3.5439days,
4.4572days, and 2.6940days, masses of 0.60MJ, 0.62MJ, and
0.80MJ, and radii of 1.57RJ, 1.73R J, and 1.68RJ,
respectively. They orbit stars with masses of 1.40 M ☉, 1.51
M☉, and 1.51 M☉, respectively. The three planets are
members of an emerging population of highly inflated Jupiters with
0.4MJ<M<1.5MJ and R>1.5RJ.
Description:
The observational procedure employed by HATNet to discover transiting
exoplanets (TEPs) has been described in detail in several previous
discovery papers (e.g., Bakos et al., 2010, cat. J/ApJ/710/1724;
Latham et al., 2009, cat. J/ApJ/704/1107). We conducted photometric
observations of three stars (HAT-P-39, HAT-P-40, and HAT-P-41) with
the KeplerCam CCD camera on the Fred Lawrence Whipple Observatory
(FLWO) 1.2m telescope, the Spectral CCD on the 2.0m Faulkes Telescope
North (FTN) at Haleakala Observatory in HI, and the CCD imager on the
Byrne Observatory at Sedgwick (BOS) 0.8m telescope, at Sedgwick
Reserve in the Santa Ynez Valley, CA. Both FTN and BOS are operated by
the Las Cumbres Observatory Global Telescope (LCOGT,
http://lcogt.net). Photometric observations of each new planetary
system are summarized below:

We obtained high-resolution, high-S/N spectra with the HIgh-Resolution
Echelle Spectrometer (HIRES) on the Keck-I telescope in HI and with
the FIbre-fed Echelle Spectrograph (FIES) on the Nordic Optical
Telescope on the island of La Palma, Spain. We used the
high-resolution fiber (providing spectra with a resolution of R=67000)
for four of the FIES observations, and the medium-resolution fiber
(R=46000) for five of the FIES observations.

Note (1): The zero point of these velocities is arbitrary. An overall offset
γrel fitted to these velocities in Section 3.3 has not been
subtracted. Note that for the iodine-free template exposures we do
not measure the radial velocities, but do measure the bisector spans
and chromospheric activity index. Such template exposures can be
distinguished by the missing radial velocities values.
Note (2): Internal errors excluding the component of astrophysical jitter
considered in Section 3.3.
