Abstract:
In this paper we present new precise atmospheric parameters for stars
with planets. We then take the opportunity to present a new catalogue
of stellar parameters for FGK and M stars with planets detected by
radial velocity, transit, and astrometry programs.
Stellar atmospheric parameters and masses for the sample were
derived assuming LTE and using high resolution and high
signal-to-noise spectra. The methodology used is based on the
measurement of equivalent widths for a list of iron lines and making
use of iron ionization and excitation equilibrium principles. For the
catalog, and whenever possible, we used parameters derived in previous
works published by our team, using well defined methodologies for the
derivation of stellar atmospheric parameters. This set of parameters
amounts to over 65% of all planet host stars known, including more
than 90% of all stars with planets discovered through radial velocity
surveys. For the remaining targets, stellar parameters were collected
from the literature.
Description:
The file sweetcat.dat contains the spectroscopic parameters for all the
planet hosts compiled for this work (data as of July 2013). Up to date
tables can be found at http://www.astro.up.pt/resources/sweet-cat .
The spectra were gathered through observations, made by our team, and
by the use of the ESO archive. In total, six different spectrographs
were used: FEROS (2.2m ESO/MPI telescope, La Silla, Chile), FIES
(Nordic Optical Telescope, La Palma, Spain), HARPS (3.6m ESO
telescope, La Silla, Chile), SARG (TNG Telescope, La Palma, Spain),
SOPHIE (1.93m telescope, OHP, France), and UVES (VLT Kueyen telescope,
Paranal, Chile).

Note (1): V magnitudes for all targets were also compiled from Simbad whenever
possible. Exceptions where no V magnitudes were listed in Simbad (for some
Kepler and WASP candidates mostly) were taken directly from the Encyclopaedia.
The V magnitudes are meant to serve as reference, and not to be used for
accurate physical calculations.
Note (2): Parallax values were compiled from Simbad whenever these exist. For
cases where the parallax is not available, we computed a "spectroscopic
parallax" using the estimated stellar parameters (for details on the method
we point to Sousa et al. 2011, Cat. J/A+A/526/A99). For M-dwarfs, a few
parallaxes were also taken from the literature.
Note (3): if flag=1 the parameters have been derived by our group.
