Gaia data release 1, the photometric data
F. van Leeuwen, D. W. Evans, F. De Angeli +91
Context. This paper presents an overview of the photometric data that are part of the first Gaia data release. Aims. The principles of the processing and the main characteristics o…
An empirical recipe for inelastic hydrogen-atom collisions in non-LTE calculations
Rana Ezzeddine, Thibault Merle, Bertrand Plez +3
We investigate the role of hydrogen collisions in NLTE spectral line synthesis, and introduce a new general empirical recipe to determine inelastic charge transfer (CT) and bound-b…
Gaia data release 1: Principles of the photometric calibration of the G band
J. M. Carrasco, D. W. Evans, P. Montegriffo +24
Context. Gaia is an ESA cornerstone mission launched on 19 December 2013 aiming to obtain the most complete and precise 3D map of our Galaxy by observing more than one billion sour…
HR8844: A new hot Am star ?
R. Monier, M. Gebran, F. Royer
Using one archival high dispersion high quality spectrum of HR8844 (A0V) obtained with the echelle spectrograph SOPHIE at Observatoire de Haute Provence, we show that this star is…
HD 30963: a new HgMn star
R. Monier, M. Gebran, F. Royer
Using high dispersion high quality spectra of HD 30963 obtained with the echelle spectrograph SOPHIE at Observatoire de Haute Provence in November 2015, we show that this star, hit…
The Rotation-Activity Correlations in K and M dwarfs. I. Stellar parameters, compilations of and for a large sample of late-K and M dwarfs
E. R. Houdebine, D. J. Mullan, F. Paletou +1
Reliable determination of Rotation-Activity Correlation (RAC's) depends on precise measurements of the following stellar parameters: , parallax, radius, metallicity, and r…
