Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
The Gaia-ESO Survey: Oxygen abundance in the Galactic thin and thick disks
Mariagrazia Franchini, Carlo Morossi, Paolo Di Marcantonio +18
We analyze the oxygen abundances of a stellar sample representative of the two major Galactic populations: the thin and thick disks. The aim is to investigate the differences betwe…
The diffuse interstellar band around 8620 Å I. Methods and application to the GIBS data set
H. Zhao, M. Schultheis, A. Recio-Blanco +6
We developed a set of procedures to automatically detect and measure the DIB around 8620 Å (the Gaia DIB) for a wide range of temperatures. The DIB profile is fit with a Gaussian f…
The chemodynamics of prograde and retrograde Milky Way stars
Georges Kordopatis, Alejandra Recio-Blanco, Mathias Schultheis +1
Context: The accretion history of the Milky Way is still unknown, despite the recent discovery of stellar systems that stand out in terms of their energy-angular momentum space, su…
An optimised tiling pattern for multi-object spectroscopic surveys: application to the 4MOST survey
E. Tempel, T. Tuvikene, M. M. Muru +22
Large multi-object spectroscopic surveys require automated algorithms to optimise their observing strategy. One of the most ambitious upcoming spectroscopic surveys is the 4MOST su…
The -Process Alliance: Fourth Data Release from the Search for -Process-Enhanced Stars in the Galactic Halo
Erika M. Holmbeck, Terese T. Hansen, Timothy C. Beers +22
This compilation is the fourth data release from the -Process Alliance (RPA) search for -process-enhanced stars, and the second release based on "snapshot" high-resolution ($…
The RAdial Velocity Experiment (RAVE): Parameterisation of RAVE spectra based on convolutional neural networks
G. Guiglion, G. Matijevic, A. B. A. Queiroz +22
In the context of large spectroscopic surveys of stars, data-driven methods are key in deducing physical parameters for millions of spectra in a short time. Convolutional neural ne…
Probabilistic fibre-to-target assignment algorithm for multi-object spectroscopic surveys
E. Tempel, P. Norberg, T. Tuvikene +22
Context. Several new multi-object spectrographs are currently planned or under construction that are capable of observing thousands of Galactic and extragalactic objects simultaneo…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- II: Stellar Atmospheric Parameters, Chemical Abundances and Distances
Matthias Steinmetz, Guillaume Guiglion, Paul J. McMillan +58
We present part 2 of the 6th and final Data Release (DR6 or FDR) of the Radial Velocity Experiment (RAVE), a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars rando…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- I: Survey Description, Spectra and Radial Velocities
Matthias Steinmetz, Gal Matijevic, Harry Enke +59
The Radial Velocity Experiment (RAVE) is a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars randomly selected in the southern hemisphere. The RAVE medium-resolutio…
The Pristine survey VIII: The metallicity distribution function of the Milky Way halo down to the extremely metal-poor regime
K. Youakim, E. Starkenburg, N. F. Martin +15
The Pristine survey uses narrow-band photometry to derive precise metallicities down to the extremely metal-poor regime ([Fe/H] < -3), and currently consists of over 4 million FGK-…
