Gaia Data Release 3: Analysis of the Gaia BP/RP spectra using the General Stellar Parameterizer from Photometry

R. Andrae, M. Fouesneau, R. Sordo, C. A. L. Bailer-Jones et autres

We present the General Stellar Parameterizer from Photometry (GSP-Phot), which is part of the astrophysical parameters inference system (Apsis). GSP-Phot is designed to produce a homogeneous catalogue of parameters for hundreds of millions of single non-variable stars based on their astrometry, photometry, …

Gaia Data Release 3: G_RVS photometry from the RVS spectra

P. Sartoretti, O. Marchal, C. Babusiaux, C. Jordi et autres

Gaia Data Release 3 (DR3) contains the first release of magnitudes estimated from the integration of Radial Velocity Spectrometer (RVS) spectra for a sample of about 32.2 million stars brighter than G_RVS~14 mag (or G~15 mag). In this paper, we describe the …

Gaia Data Release 3: Hot-star radial velocities

R. Blomme, Y. Fremat, P. Sartoretti, A. Guerrier et autres

The second Gaia data release, DR2, contained radial velocities of stars with effective temperatures up to Teff = 6900 K. The third data release, Gaia DR3, extends this up to Teff = 14,500 K. We derive the radial velocities for hot stars …
