Map of observed Gaia-ESO targets on the sky. Observations shown are those included in internal data release 6 (iDR6), covering the entire observing period of the Survey, from 31/12/2011-26/01/2018. Key: MW = Milky Way, CL = Cluster, SD = Standard.

Fifth Gaia-ESO Data Release: the Catalogue with the Astrophysical Parameters for ~115,000 Stars

The DR5.0 release includes all the astrophysical parameters derived by the Gaia-ESO consortium for 114,324 stars. In detail the catalogue provides:

  • the radial and projected rotational velocities,
  • stellar parameters (effective temperature, surface gravity and metallicity),
  • abundances of several elements,
  • specific parameters for tracing accretion and activity in young stars,
  • for the targets of the cluster fields the cluster probability membership is provided, calculated combining Gaia-ESO radial velocities with astrometry from Gaia EDR3 release (Jackson et al, 2022).

More information about the release content can be found in the accompanying documentation. The fifth data release from the Gaia-ESO survey is now available on the ESO archive, and it is accessible to the community via the ESO Catalogue Facility, programmatically, and via the Science Portal (specifically the catalogue preview gives you instantaneous access to the histograms of all the catalogues columns).

The Gaia ESO science catalogue published in the DR5.0 has been produced by the PIs and their collaborators, including CASU.
