New constraints on the chemical evolution of the solar neighbourhood and Galactic disc(s) Improved astrophysical parameters for the Geneva-Copenhagen Survey
(EDP SCIENCES S A, 2011)
We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and uses the latter to build a consistent and ...
The Gaia-ESO Survey: a quiescent Milky Way with no significant dark/stellar accreted disc(a similar to...)
(OXFORD UNIV PRESS, 2015)
According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will be dragged towards the disc plane, ...
TESS Reveals a short-period sub-neptune sibling (HD 86226c) to a known long-period giant planet
(IOP Publishing Ltd, 2020)
The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby
stars. Here, we present the detection and mass measurement of a small, short-period (≈4 days) transiting ...
Stellar activity as a tracer of moving groups
(EDP Sciences, 2013)
We present the results of a study of the stellar activity in the solar neighborhood using complete kinematics (galactocentric velocities
U, V, W) and the chromospheric activity index log R0
HK. We analyzed the average ...
Planck 2015 results I. Overview of products and scientific results
(Edp Sciences S A, 2016-10-01)
The European Space Agency's Planck satellite, which is dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between ...
Planck 2015 results XVII. Constraints on primordial non-Gaussianity
(Edp Sciences S A, 2016-10-01)
The Planck full mission cosmic microwave background (CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non-Gaussianity (NG). Using three classes of optimal bispectrum estimators ...
