Abstract:
We report the discovery of four transiting extrasolar planets
(HAT-P-34b-HAT-P-37b) with masses ranging from 1.05 to 3.33MJ and
periods from 1.33 to 5.45days. These planets orbit relatively bright F
and G dwarf stars (from V=10.16 to V=13.2). Of particular interest is
HAT-P-34b which is moderately massive (3.33MJ), has a high
eccentricity of e=0.441±0.032 at a period of
P=5.452654±0.000016days, and shows hints of an outer component. The
other three planets have properties that are typical of hot Jupiters.
Description:
High-resolution, low-S/N "reconnaissance" spectra were obtained using
the Tillinghast Reflector Echelle Spectrograph (TRES) on the 1.5m
Tillinghast Reflector at FLWO (see Section 2.2 for more details).
High-resolution, high-S/N spectra were obtained in 2010 and 2011 using
HIRES on the 10m Keck I telescope in Hawaii, the High-Dispersion
Spectrograph (HDS) on the 8.3m Subaru telescope in Hawaii, the
FIbre-fed Echelle Spectrograph (FIES) on the 2.5m Nordic Optical
Telescope (NOT) at La Palma, Spain, and TRES on the FLWO 1.5m
telescope (see Section 2.3 for more details).
Photometric observations were conducted in 2010 and 2011 using the
KeplerCam CCD camera on the FLWO 1.2m telescope, and the Spectral
Instrument CCD on the 2.0m Faulkes Telescope North (FTN) at Haleakala
Observatory in Hawaii, which is operated by the Las Cumbres
Observatory Global Telescope (LCOGT) (see Section 2.4 for more
details).

--------------------------------------------------------------------------------
Note (2): Note that the apparent depth of the HATNet transit for all four
targets is shallower than the true transit depth due to blending with
unresolved neighbors in the low spatial resolution HATNet images (the
median FWHM of the point-spread function at the center of a HATNet
image is ∼25"). Also, we applied the trend-filtering procedure in
non-signal-reconstructive mode, which reduces the transit depth while
increasing the signal-to-noise ratio of the detection. For each
system, the ratio of the planet and stellar radii, which is related to
the true transit depth, is determined in Section 3.2 using the higher
spatial resolution photometric follow-up observations described in
Section 2.4.

Note (1):
d = The FIES/NOT observations of HAT-P-35 were not used in the analysis,
see the footnote to Table 4. Transit ingress began during the hour-long
exposure obtained at phase 0.973, and the exposure obtained at phase 0.344
has a low S/N ratio and was obtained during morning twilight.
Note (2): The zero point of these velocities is arbitrary. An overall
offset γrel fitted to these velocities in Section 3.2 has not
been subtracted.
Note (3): Internal errors excluding the component of astrophysical jitter
considered in Section 3.2.
Note (4): Chromospheric activity index calibrated to the scale of Vaughan
et al. (1978PASP...90..267V 1978PASP...90..267V).
