Abstract:
We report the discovery and characterization of seven transiting
exoplanets from the HATNet survey. The planets, which are hot Jupiters
and Saturns transiting bright Sun-like stars, include: HAT-P-58b (with
mass Mp=0.37MJ, radius Rp=1.33RJ, and orbital period
P=4.0138days), HAT-P-59b (Mp=1.54MJ, Rp=1.12RJ, P=4.1420days),
HAT-P-60b (Mp=0.57MJ, Rp=1.63RJ, P=4.7948days), HAT-P-61b
(Mp=1.06MJ, Rp=0.90RJ, P=1.9023days), HAT-P-62b
(Mp=0.76MJ, Rp=1.07RJ, P=2.6453days), HAT-P-63b
(Mp=0.61MJ, Rp=1.12RJ, P=3.3777days), and HAT-P-64b
(Mp=0.58MJ, Rp= 1.70RJ, P=4.0072days). The typical errors on
these quantities are 0.06MJ, 0.03RJ, and 0.2s, respectively. We
also provide accurate stellar parameters for each of the host stars.
With V=9.710±0.050mag, HAT-P-60 is an especially bright transiting
planet host, and an excellent target for additional follow-up
observations. With Rp=1.703±0.070RJ, HAT-P-64b is a highly
inflated hot Jupiter around a star nearing the end of its
main-sequence lifetime, and is among the largest known planets. Five
of the seven systems have long-cadence observations by TESS which are
included in the analysis. Of particular note is HAT-P-59 (TOI-1826.01)
which is within the northern continuous viewing zone of the TESS
mission, and HAT-P-60, which is the TESS candidate TOI-1580.01.
Description:
We presented the discovery of seven hot Jupiters transiting bright
stars. These planets were first identified as transiting planet
candidates by the HATNet survey from among some six million stars that
have been observed to date since 2004. They were subsequently
confirmed and accurately characterized using high-precision
time-series photometry from Fred Lawrence Whipple Observatory (FLWO)
1.2 m/KeplerCam, and the NASA Transiting Exoplents Survey Satellite
(TESS) mission, and high-resolution spectroscopy, enabling
high-precision RVel measurements, carried out with the FLWO 1.5m/TRES
(Tillinghast Reflector Echelle Spectrograph), Keck-I/HIRES (High
Resolution Echelle Spectrometer), Observatoire de Haute Provence (OHP)
1.93m/SOPHIE, Subaru 8m/HDS, Apache Point Observatory (APO)
3.5m/ARCES, Nordic Optical Telescope (NOT) 2.5m/FIES (fiber-fed
echelle Spectrograph), and Las Cumbres Observatory Grand Telescope
(LCOGT) 1m/NRES telescopes/instruments. Filters, dates and resolutions
can be found in table 1, 2 and 3.

Note (1): On the dynamical time system, including the correction for
leap seconds.
Note (2): The out-of-transit level has been subtracted. For observations made
with the HATNet instruments (identifed by "HATNet" in the last column)
these magnitudes have been corrected for trends using the EPD and TFA
procedures applied either prior to fitting the transit model, or in
conjunction with fitting a box-shaped transit. This procedure,
together with blending for nearby stars, may lead to an artificial
dilution in the transit depths. The blend factors for the HATNet
light curves are listed in Tables 10 and 11. For observations made
with follow-up instruments (anything other than "HATNet" in the last
column), the magnitudes have been corrected for a quadratic trend in
time, for variations correlated with three PSF shape parameters, and
for trends correlated with variations seen in the light curves of
other stars in the field (the TFA method) fit simultaneously with
the transit.
Note (3): Raw magnitude values without correction for the quadratic trend in
time, for trends correlated with the shape of the PSF, or application
of TFA. These are only reported for the follow-up observations.
