The Gaia -ESO Survey : Empirical determination of the precision of stellar radial velocities and projected rotation velocities
(2015-08)
Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims. A key aim is to provide precise radial velocities (RVs) and projected equatorial ...
New OB star candidates in the Carina Arm around Westerlund 2 from VPHAS+
(2015-07-11)
O and early B stars are at the apex of galactic ecology, but in the Milky Way, only a minority of them may yet have been identified. We present the results of a pilot study to select and parametrise OB star candidates in ...
Gaia-ESO Survey : Analysis of pre-main sequence stellar spectra
(2015-04-01)
Context. The Gaia-ESO Public Spectroscopic Survey is obtaining high-quality spectroscopy of some 100 000 Milky Way stars using the FLAMES spectrograph at the VLT, down to V = 19 mag, systematically covering all the main ...
The Gaia-ESO Survey : Extracting diffuse interstellar bands from cool star spectra: DIB-based interstellar medium line-of-sight structures at the kpc scale
(2015-01)
Aims. We study how diffuse interstellar bands (DIBs) measured toward distance-distributed target stars can be used to locate dense interstellar (IS) clouds in the Galaxy and probe a line-of-sight (LOS) kinematical structure, ...
The Gaia-ESO Survey : The analysis of high-resolution UVES spectra of FGK-type stars
(2014-11)
Context. The ongoing Gaia-ESO Public Spectroscopic Survey is using FLAMES at the VLT to obtain high-quality medium-resolution Giraffe spectra for about 105 stars and high-resolution UVES spectra for about 5000 stars. With ...
A 3D extinction map of the northern Galactic plane based on IPHAS photometry
(2014-10-01)
We present a 3D map of extinction in the northern Galactic plane derived using photometry from the INT/WFC Photometric Hα Survey of the northern Galactic plane. The map has fine angular (~10 arcmin) and distance (100 pc) ...
First release of the IPHAS catalogue of new extended planetary nebulae
(2014-10-01)
We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the Isaac Newton Telescope Photometric Ha Survey of the Northern ...
High proper motion objects from the UKIDSS Galactic plane survey
(2014-09-21)
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a seven year effort to survey ~1800 deg2 of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K-band data, with a baseline ...
The Gaia-ESO Survey : Stellar content and elemental abundances in the massive cluster NGC 6705
(2014-09)
Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical ...
Gaia-ESO Survey : Empirical classification of VLT/Giraffe stellar spectra in the wavelength range 6440-6810 Å in the γ Velorum cluster, and calibration of spectral indices
(2014-06)
We present a study of spectral diagnostics available from optical spectra with R = 17 000 obtained with the VLT/Giraffe HR15n setup, using observations from the Gaia-ESO Survey, on the γ Vel young cluster, with the purpose ...
