Spectroscopic analysis of RGB stars in nine open clusters
Saulo de Oliveira Cantanhêde, Alan Alves-Brito, Rodolfo Smiljanic +4
Stellar clusters are crucial tools for studying the age, spatial distribution, dynamics, kinematics, and chemical composition of different Galactic stellar populations. In this wor…
The Gaia mission
L. Eyer, B. Holl, D. Pourbaix +5
Gaia is a very ambitious mission of the European Space Agency. At the heart of Gaia lie the measurements of the positions, distances, space motions, brightnesses and astrophysical…
Automated spectroscopic abundances of A and F-type stars using echelle spectrographs II. Abundances of 140 A-F stars from ELODIE and CORALIE
D. Erspamer, P. North
Using the method presented in Erspamer & North (2002, Paper I hereafter), detailed abundances of 140 stars are presented. The uncertainties characteristic of this method are presen…
Multiplicity among chemically peculiar stars II. Cool magnetic Ap stars
F. Carrier, P. North, S. Udry +1
We present new orbits for sixteen Ap spectroscopic binaries, four of which might in fact be Am stars, and give their orbital elements. Four of them are SB2 systems: HD 5550, HD 221…
Physical parameters of the Algol system TZ Eridani from simultaneous analysis of Geneva 7-colour light curves
F. Barblan, P. Bartholdi, P. North +2
Light curves of the semi-detached eclipsing binary system TZ Eridani in the Geneva 7-colour photometric system were analysed using the Wilson-Devinney programme. The physical and o…
Multiplicity among peculiar A stars I. The Ap stars HD 8441 and HD 137909, and the Am stars HD 43478 and HD 96391
P. North, J. -M. Carquillat, N. Ginestet +2
We present the first results of a radial-velocity survey of cool Ap and Am stars. HD 8441 is not only a double system with P = 106.357 days, but is a triple one, the third companio…
