Abstract:
To improve the parameters of the HD17156 system (peculiar due to
the eccentric and long orbital period of its transiting planet) and
constrain the presence of stellar companions. Photometric data were
acquired for 4 transits, and high precision radial velocity
measurements were simultaneously acquired with SARG at TNG for one
transit. The template spectra of HD 17156 was used to derive effective
temperature, gravity, and metallicity. A fit of the photometric and
spectroscopic data was performed to measure the stellar and planetary
radii, and the spin-orbit alignment. Planet orbital elements and
ephemeris were derived from the fit. Near infrared adaptive optic
images was acquired with ADOPT at TNG. We have found that the star
has a radius of RS=1.44±0.03R☉ and the planet
RP=1.02±0.08R{jup} The transit ephemeris is
Tc=2454756.73134±0.00020+N*21.21663±0.00045 BJD.
The analysis of the Rossiter-Mclaughlin effect shows that the system
is spin orbit aligned with an angle Beta=4.8±5.3deg The analysis of
high resolution images has not revealed any stellar companion with
projected separation between 150 and 1000 AU from HD17156. Here we
present the photometric data of the transits of HD 17156b.
Description:
This table contains the photometric time serie obtained for a series
of transits of the planet HD 17156b. The first column gives the date
as Barycentric Julian Days (BJD), the second one gives the flux
normalized to the out-of-transit average value, and the third one
gives the Identification code of each observation.
