The Gaia-ESO Survey : the N/O abundance ratio in the Milky Way
(2018-10-01)
Context. The abundance ratio N/O is a useful tool to study the interplay of galactic processes, for example star formation e ciency, timescale of infall, and outflow loading factor. Aims. We aim to trace log(N/O) versus ...
The Gaia-ESO Survey: pre-main-sequence stars in the young open cluster NGC 3293
(2016-08-11)
The young open cluster NGC3293 is included in the observing program of the Gaia-ESO survey (GES). The radial velocity values provided have been used to assign cluster membership probabilities by means of a single-variable ...
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 ...
