Gaia will obtain astrometry and spectrophotometry for essentially all sources in the sky down to a broad band magnitude limit of G=20, an expected yield of 10^9 stars. Its main scientific objective is to reveal the formation and evolution of our Galaxy through chemo-dynamical analysis. In addition to inferring positions, parallaxes and proper motions from the astrometry, we must also infer the astrophysical parameters of the stars from the spectrophotometry, the BP/RP spectrum. Here we… 
The Gaia astrophysical parameters inference system (Apsis) - Pre-launch description
The Gaia satellite will survey the entire celestial sphere down to 20th magnitude, obtaining astrometry, photometry, and low resolution spectrophotometry on one billion astronomical sources, plus
Fundamental stellar parameters and metallicities from Bayesian spectroscopy: application to low- and high-resolution spectra
We present a novel method based on Bayesian inference to derive physical parameters of stars from any observed data. Here we focus on log(g), Teff, [Fe/H], age, mass, and distance of a star. As an
Strömgren-Crawford uvbyβ all sky survey - towards understanding of the Galaxy
Abstract The Strömgren-Crawford (SC) intermediate-band photometric system is a very powerful and efficient one for the detailed study of stars, and therefore the Milky Way and local universe.
Stellar parametrization from Gaia RVS spectra
Among the myriad of data collected by the ESA Gaia satellite, about 150 million spectra will be delivered by the Radial Velocity Spectrometer (RVS) for stars as faint as G_RVS~16. A specific stellar
Detecting stars, galaxies, and asteroids with Gaia
(Abridged) Gaia aims to make a 3-dimensional map of 1,000 million stars in our Milky Way to unravel its kinematical, dynamical, and chemical structure and evolution. Gaia's on-board detection
Properties of ultra-cool dwarfs with Gaia - An assessment of the accuracy for the temperature determination
Context. The Gaia catalogue will contain observations and physical parameters of a vast number of objects, including ultra-cool dwarf stars, which we define here as stars with a temperature below
Aurigaia: mock Gaia DR2 stellar catalogues from the auriga cosmological simulations
We present and analyse mock stellar catalogues that match the selection criteria and observables (including uncertainties) of the Gaia satellite data release 2 (DR2). The source are six cosmological
A large sample of calibration stars for Gaia: log g from Kepler and CoRoT fields
Asteroseismic data can be used to determine surface gravities with precisions of < 0.05 dex by using the global seismic quantities Deltanu and nu_max along with Teff and [Fe/H]. Surface gravity is
Measuring stars with Gaia
Beyond the extraordinary three dimensional map that Gaia will create for a billion of stars, it will reveal the origin and history of the Milky Way as the major goal. This does not weakness the
Chemical Mapping of the Milky Way with The Canada-France Imaging Survey: A Non-parametric Metallicity-Distance Decomposition of the Galaxy
We present the chemical distribution of the Milky Way, based on 2900 of u-band photometry taken as part of the Canada–France Imaging Survey. When complete, this survey will cover 10,000 of the

Bayesian inference of stellar parameters and interstellar extinction using parallaxes and multiband photometry
Astrometric surveys provide the opportunity to measure the absolute magnitudes of large numbers of stars, but only if the individual line-of-sight extinctions are known. Unfortunately, extinction is

Photometric constraints on white dwarfs and the identification of extreme objects
It is possible to reliably identify white dwarfs (WDs) without recourse to spectra, instead using photometric and astrometric measurements to distinguish them from main-sequence stars and quasars.
