Journal ArticleDOI
HIP 21539 is not a past very close neighbour of the Sun
TL;DR: In this article, a new accurate radial velocity from the HARPS spectrograph combined with the recent Gaia-TGAS astrometry was used to determine the trajectory of the star HIP 21539 relative to the Sun.
Journal ArticleDOI
The Milky Way's halo in 6D: Gaia's Radial Velocity Spectrometer performance
George M. Seabroke,Mark Cropper,David Katz,P. Sartoretti,Pasquale Panuzzo,Olivier Marchal,A. Gueguen,Kevin Benson,C. Dolding,H. E. Huckle,Michael D. Smith,Steve Baker +11 more
TL;DR: In this article, the authors illustrate the implications of the RVS limiting magnitude on Gaia's view of the Milky Way's halo in 6D using the Gaia Universe Model Snapshot (GUMS).
Journal ArticleDOI
Radial velocities, dynamics of stars and nebulosities with GAIA and VLT-GIRAFFE
Christophe Martayan,Yves Fremat,Ronny Blomme,A. Jonckheere,Celine Delle-Luche,P. Sartoretti,David Katz,Y. Viala,Michele Floquet,Anne-Marie Hubert,Coralie Neiner +10 more
TL;DR: In this paper, the radial velocities distributions for B-type stars and nebulosities observed with the VLT-GIRAFFE in the Largeand Small Magellanic Clouds towards the open clustersNGC2004 and NGC330.

The Milky Way's halo in 6D: Gaia's Radial Velocity Spectrometer performance

TL;DR: In this article, the end-of-mission radial velocity (RV) performance requirement for G2V stars was 15 km s−1 at V = 16.5 mag, consistent with simulations that predict a loss of 1.4 mag.
Journal ArticleDOI
HIP 21539 is not a past very close neighbour of the Sun
TL;DR: The trajectory of the star HIP 21539 is redetermined using a new accurate radial velocity from the HARPS spectrograph combined with the recent Gaia-TGAS astrometry, which shows that at this distance, the star has not perturbed the Oort cloud.
