This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Solar-like oscillations in the G8 V star tau Ceti
T. C. Teixeira, H. Kjeldsen, T. R. Bedding +8
We used HARPS to measure oscillations in the low-mass star tau Cet. Although the data were compromised by instrumental noise, we have been able to extract the main features of the…
Galaxy evolution in Abell 85: I. Cluster substructure and environmental effects on the blue galaxy population
H. Bravo-Alfaro, C. A. Caretta, C. Lobo +2
This series of papers explores the evolution of late-type galaxies in the rich cluster Abell 85. Here, we revisit the complex dynamical state of A 85 by using independent methods.…
Metallicities for 13 nearby open clusters from high-resolution spectroscopy of dwarf and giant stars. Stellar metallicity, stellar mass, and giant planets
N. C. Santos, C. Lovis, G. Pace +2
We present a study of accurate stellar parameters and iron abundances for 39 giants and 16 dwarfs in the 13 open clusters IC2714, IC4651, IC4756, NGC2360, NGC2423, NGC2447 (M93), N…
Testing gravity on large scales. The skewness of the galaxy distribution at z~1
C. Marinoni, L. Guzzo, A. Cappi +54
We study the evolution of the low-order moments of the galaxy overdensity distribution over the redshift interval 0.7<z<1.5. We find that the variance and the normalized skewness e…
Physical properties of galaxies and their evolution in the VIMOS VLT Deep Survey. II. Extending the mass-metallicity relation to the range z=0.89-1.24
E. Perez-Montero, T. Contini, F. Lamareille +39
Aims. We present a continuation of our study about the relation between stellar mass and gas-phase metallicity in the VIMOS VLT Deep Survey (VVDS). In this work we extend the deter…
Physical properties of galaxies and their evolution in the VIMOS VLT Deep Survey. I. The evolution of the mass-metallicity relation up to z~0.9
F. Lamareille, J. Brinchmann, T. Contini +43
We derive the mass-metallicity relation of star-forming galaxies up to , using data from the VIMOS VLT Deep Survey. Automatic measurement of emission-line fluxes and equi…
The VVDS-VLA Deep Field - IV: Radio-optical properties
S. Bardelli, E. Zucca, M. Bolzonella +51
(abridged) We use the 1.4 GHz VIMOS-VLA Deep Survey and the optical VVDS and the CFHT-LS to compare the properties of radio loud galaxies with respect to the whole population of op…
Stellar activity of planetary host star HD 189733
I. Boisse, C. Moutou, A. Vidal-Madjar +20
Extra-solar planet search programs require high-precision velocity measurements. They need to study how to disentangle radial-velocity variations due to Doppler motion from the noi…
The HARPS search for southern extra-solar planets XVII. Six long-period giant planets around BD -17 0063, HD 20868, HD 73267, HD 131664, HD 145377, HD 153950
C. Moutou, M. Mayor, G. Lo Curto +8
We report the discovery of six new substellar companions of main-sequence stars, detected through multiple Doppler measurements with the instrument HARPS installed on the ESO 3.6m…
Phase Closure Image Reconstruction for Future VLTI Instrumentation
Mercedes E. Filho, Stephanie Renard, Paulo Garcia +21
Classically, optical and near-infrared interferometry have relied on closure phase techniques to produce images. Such techniques allow us to achieve modest dynamic ranges. In order…
Phase Referencing in Optical Interferometry
Mercedes E. Filho, Paulo Garcia, Gilles Duvert +20
One of the aims of next generation optical interferometric instrumentation is to be able to make use of information contained in the visibility phase to construct high dynamic rang…
The HARPS search for southern extra-solar planets: XIV. Gl 176b, a super-Earth rather than a Neptune, and at a different period
T. Forveille, X. Bonfils, X. Delfosse +10
A 10.24 days Neptune-mass planet was recently announced to orbit the nearby M2 dwarf Gl 176, based on 28 radial velocities measured with the HRS spectrograph on the Hobby-Heberly T…
