A study of the F-giant star Scorpii A: a post-merger rapid rotator?
Fiona Lewis, Jeremy Bailey, Daniel V. Cotton +3
We report high-precision observations of the linear polarization of the F1III star Scorpii. The polarization has a wavelength dependence of the form expected for a rapid ro…
Internal calibration of Gaia BP/RP low-resolution spectra
J. M. Carrasco, M. Weiler, C. Jordi +6
The full third Gaia data release will provide the calibrated spectra obtained with the blue and red Gaia slit-less spectrophotometers. The main challenge when facing Gaia spectral…
The distance, rotation, and physical parameters of zeta Pup
Ian D. Howarth, Floor van Leeuwen
We scrutinize the Hipparcos parallax for the bright O supergiant zeta Pup, and confirm that the implied distance of 332+/-11pc appears to be reliable. We then review the implicatio…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
Gaia Data Release 2: Properties and validation of the radial velocities
D. Katz, P. Sartoretti, M. Cropper +51
For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…
Gaia Data Release 2: Kinematics of globular clusters and dwarf galaxies around the Milky Way
Gaia Collaboration, A. Helmi, F. van Leeuwen +7
The goal of this paper is to demonstrate the outstanding quality of the second data release of the Gaia mission and its power for constraining many different aspects of the dynamic…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Impact of basic angle variations on the parallax zero point for a scanning astrometric satellite
Alexey G. Butkevich, Sergei A. Klioner, Lennart Lindegren +2
Determination of absolute parallaxes by means of a scanning astrometric satellite such as Hipparcos or Gaia relies on the short-term stability of the so-called basic angle between…
Gaia Data Release 1: Validation of the photometry
D. W. Evans, M. Riello, F. De Angeli +12
Aims. The photometric validation of the Gaia DR1 release of the ESA Gaia mission is described and the quality of the data shown. Methods. This is carried out via an internal analys…
Gaia data release 1, the photometric data
F. van Leeuwen, D. W. Evans, F. De Angeli +91
Context. This paper presents an overview of the photometric data that are part of the first Gaia data release. Aims. The principles of the processing and the main characteristics o…
On-orbit performance of the Gaia CCDs at L2
C. Crowley, R. Kohley, N. C. Hambly +19
The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mi…
Gaia on-board metrology: basic angle and best focus
A. Mora, M. Biermann, A. G. A. Brown +21
The Gaia payload ensures maximum passive stability using a single material, SiC, for most of its elements. Dedicated metrology instruments are, however, required to carry out two f…
The Hipparcos parallax for Polaris
Floor van Leeuwen
This letter follows a recent claim that the Hipparcos parallax for Polaris could be too small by 2.5 mas. It examines in detail the Hipparcos epoch astrometric data for Polaris, as…
