Gaia DR3. 95 extrasolar planets
Listed in IVOA Registry (Virtual Observatory)
Gaia Data Release 3 provides a wealth of new data products for the astronomical community to exploit, including astrophysical parameters for a half billion stars.
Description
In this work we demonstrate the high quality of these data products and illustrate their use in different astrophysical contexts. We have produced six homogeneous samples of stars with high quality astrophysical parameters across the HR diagram for the community to exploit.
We first focus on three samples that span a large parameter space: young massive disk stars (OBA), FGKM spectral-type stars, and ultra-cool dwarfs (UCDs). We provide these sources along with additional information (either a flag or complementary parameters) as tables that are made available in the Gaia archive. We furthermore identify 15740 bone fide carbon stars, 5863 solar-analogues, and provide the first homogeneous set of stellar parameters of the Spectro Photometric Standard Stars.

We demonstrate some applications of these samples in different astrophysical contexts. We use a subset of the OBA sample to illustrate its usefulness to analyse the Milky Way rotation curve. We then use the properties of the FGKM stars to analyse known exoplanet systems.
We also analyse the ages of some unseen UCD-companions to the FGKM stars. We additionally predict the colours of the Sun in various passbands (Gaia, 2MASS, WISE) using the solar-analogue sample.
