obtain astrophysical parameters and elemental abundances for 100 000 stars, including …

Planck has mapped the microwave sky in temperature over nine frequency bands between
30 and 857 GHz and in polarization over seven frequency bands between 30 and 353 GHz …

Context. For Gaia DR2, 280 million spectra collected by the Radial Velocity Spectrometer
instrument on board Gaia were processed, and median radial velocities were derived for 9.8 …

among the major constraints to disentangling the scenarios of formation and evolution of the …

Spectroscopy from the final internal data release of the Gaia–ESO Survey (GES) has been
combined with Gaia EDR3 to assign membership probabilities to targets observed towards …
