Abstract:
We report the discovery of four transiting hot Jupiters from the
HATSouth survey: HATS-39b, HATS-40b, HATS-41b, and HATS-42b. These
discoveries add to the growing number of transiting planets orbiting
moderately bright (12.5≤V≤13.7) F dwarf stars on short (2-5d)
periods. The planets have similar radii, ranging from
1.33+0.29-0.20RJ for HATS-41b to 1.58+0.16-0.12RJ for
HATS-40b. Their masses and bulk densities, however, span more than an
order of magnitude. HATS-39b has a mass of 0.63±0.13MJ, and an
inflated radius of 1.57±0.12RJ, making it a good target for future
transmission spectroscopic studies. HATS-41b is a very massive
9.7±1.6MJ planet and one of only a few hot Jupiters found to date
with a mass over 5MJ. This planet orbits the highest metallicity
star ([Fe/H]=0.470±0.010) known to host a transiting planet and is
also likely on an eccentric orbit. The high mass, coupled with a
relatively young age (1.34+0.31-0.51Gyr) for the host star, is a
factor that may explain why this planet's orbit has not yet
circularized.
Description:
The HATSouth data for these targets span a period of just under two
years, from 2011 August to 2013 April, resulting in a total of
16488 data points for HATS-39, 27476 for HATS-40, 11938 for HATS-41,
and 21210 for HATS-42.
The initial follow-up phase for HATSouth planet candidates utilized
spectra acquired with the WiFeS instrument on the 2.3 m ANU telescope
at SSO.
Exposures were taken with the High Accuracy Radial Velocity Planet
Searcher (HARPS), fed by the ESO 3.6m telescope at a resolving power
of R∼115000, the FEROS spectrograph (R∼48000) fed by the MPG 2.2m
telescope, and spectra at R∼60000 were also taken with the CORALIE
spectrograph fed by the 1.2m Euler telescope, all located at La Silla
Observatory, Chile.

Note (1): The first value is determined from the global fit to the light curves
and radial-velocity data, without imposing a constraint that the parameters
match the stellar evolution models. The second value results from restricting
the posterior distribution to combinations of rho*+Teff+[Fe/H] that match
to a YY stellar model.

Note (1): Barycentric Julian Date is computed directly from the UTC time
without correction for leap seconds
Note (2): The out-of-transit level has been subtracted. For observations made
with the HATSouth instruments (identified by 'HS' in the 'Instrument' column)
these magnitudes have been corrected for trends using the EPD and TFA
procedures applied prior to fitting the transit model. This procedure may
lead to an artificial dilution in the transit depths. The blend factors for
the HATSouth light curves are listed in Table 6. For observations made with
follow-up instruments (anything other than 'HS' in the 'Instrument' column),
the magnitudes have been corrected for a quadratic trend in time, and for
variations correlated with up to three PSF shape parameters, fit
simultaneously with the transit.
Note (3): Raw magnitude values without correction for the quadratic trend in
time, or for trends correlated with the seeing. These are only reported for
the follow-up observations.
