Abstract:
SWEET-Cat (Stars With ExoplanETs Catalogue) was originally introduced
in 2013, and since then, the number of confirmed exoplanets has
increased significantly. A crucial step for a comprehensive
understanding of these new worlds is the precise and homogeneous
characterization of their host stars. We used a large number of
high-resolution spectra to continue the addition of new stellar
parameters for planet-host stars in SWEET-Cat following the new
detection of exoplanets listed both at the Extrasolar Planets
Encyclopedia and at the NASA exoplanet archive. We obtained
high-resolution spectra for a significant number of these planet-host
stars, either observed by our team or collected through public
archives. For FGK stars, the spectroscopic stellar parameters were
derived for the spectra following the same homogeneous process using
ARES+MOOG as for the previous SWEET-Cat releases. The stellar
properties are combined with the planet properties to study possible
correlations that could shed more light into the star-planet
connection studies. We increase the number of stars with homogeneous
parameters by 232 (∼25% - from 959 to 1191). We then focus on the
exoplanets with both mass and radius determined to review the
mass-radius relation where we find consistent results with the ones
previously reported in the literature. For the massive planets we also
revisit the radius anomaly where we confirm a metallicity correlation
for the radius anomaly already hinted in previous results.

and used for this paper. Please note that SWEET-Cat continues to be
updated from time to time to keep up with the new discoveries of
planet-host stars. The current updated table can be obtained in the
