Abstract:
Exoplanets have now been proven to be very common. The number of its
detections continues to grow following the development of better
instruments and missions. One key step for the understanding of these
worlds is their characterization, which mostly depend on their host
stars. We perform a significant update of the Stars With ExoplanETs
CATalog (SWEET-Cat), a unique compilation of precise stellar
parameters for planet-host stars provided for the exoplanet community.
We made use of high-resolution spectra for planet-host stars, either
observed by our team or found in several public archives. The new
spectroscopic parameters were derived for the spectra following the
same homogeneous process (ARES+MOOG). The host star parameters were
then merged together with the planet properties listed in exoplanet.eu
to perform simple data analysis. We present new spectroscopic
homogeneous parameters for 106 planet-host stars. Sixty-three planet
hosts are also reviewed with new parameters. We also show that there
is a good agreement between stellar parameters derived for the same
star but using spectra obtained from different spectrographs. The
planet-metallicity correlation is reviewed showing that the
metallicity distribution of stars hosting low-mass planets (below
30M☉) is indistinguishable from that from the solar neighborhood
sample in terms of metallicity distribution.
