Exoplanets
Stellar Characterization
Planet formation and evolution
<p>SWEET-Cat, a catalogue of Stars With ExoplanETs was originally introduced in 2013, and since then, many more exoplanets were confirmed increasing significantly the number of host stars listed there. A crucial step for a comprehensive understanding of these new worlds is the precise and homogeneous characterization of their host stars. Better spectroscopic stellar parameters along with new results from Gaia eDR3 provide updated and precise parameters for the discovered planets. A new version of the catalogue is now available to the community, whose homogeneity in the derivation of the parameters is key to unravel star-planet connections. Here we review the updated metallicity distributions of stars hosting planets. We present the current status of different planet-host populations (e.g. low-mass planet host stars, Jupiter-like host stars) which provide observational statistical constrains for the theory of planet formation and evolution. Since SWEET-Cat continues to be updated with the new discoveries of exoplanets it could be also very useful for PLATO, in particular it can be used to access the validation of the already known planet-host stars that will be listed in the PLATO Input Catalogue.</p>
