The Gaia-ESO Survey: pre-main-sequence stars in the young open cluster NGC 3293
(OXFORD UNIV PRESS, 2016-05)
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: Double-, triple-, and quadruple-line spectroscopic binary candidates
(EDP Sciences, 2017)
Context. The Gaia-ESO Survey (GES) is a large spectroscopic survey that provides a unique opportunity to study the distribution of spectroscopic multiple systems among different populations of the Galaxy. Aims. Our aim is ...
The Gaia -ESO Survey: Open clusters in Gaia -DR1: A way forward to stellar age calibration
(EDP Sciences, 2018-04)
Context. Determination and calibration of the ages of stars, which heavily rely on stellar evolutionary models, are very challenging, while representing a crucial aspect in many astrophysical areas. Aims. We describe the ...
The Gaia -ESO Survey: The origin and evolution of s -process elements
(EDP Sciences, 2018-09)
Context. Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations. These trends provide important constraints on stellar and Galactic ...
