Context. Ages, chemical compositions, velocity vectors, and Galactic orbits for stars in the solar neighbourhood are fundamental test data for models of Galactic evolution. The Geneva-Copenhagen Survey of the Solar Neighbourhood (Nordstrom et al. 2004; GCS), a magnitude-complete, kinematically unbiased sample of 16 682 nearby F and G dwarfs, is the largest available sample with complete data for stars with ages spanning that of the disk. Aims. We aim to improve the accuracy of the GCS data by…

Phosphorus Abundances in the Hyades and Galactic Disk
We have measured phosphorus abundances in nine disk stars between -1 $ $ = -0.01 $\pm$ 0.06 and $ $ = 0.03 $\pm$ 0.03 dex for the three giants. The consistency suggests abundances derived using the
The age–velocity dispersion relation of the Galactic discs from LAMOST–Gaia data
We present the age-velocity dispersion relation (AVR) in three dimensions in the solar neighbourhood using 3,564 commonly observed sub-giant/red-giant branch stars selected from LAMOST, which gives
Asymmetric metallicity patterns in the stellar velocity space with RAVE
Context. The chemical abundances of stars encode information on their place and time of origin. Stars formed together in e.g. a cluster, should present chemical homogeneity. Also disk stars
Impact of cosmological satellite galaxies on the dynamics of the Milky Way disc
I present a high resolution study of the impact of realistic satellite galaxies, extracted from cosmological simulations of Milky Way-like haloes including 6 Aquarius and one Via Lactea II suites,
Determining Ages of APOGEE Giants with Known Distances
We present a sample of local red giant stars observed using the New Mexico State University 1 m telescope with the APOGEE spectrograph, for which we estimate stellar ages and the age distribution
Dynamical information along with survey data on metallicity and in some cases age have been used recently by some authors to search for candidates of stars that were born in the cluster where the Sun
Solar analogues and solar twins in the HARPS archive
We present 63 Solar analogues and twins for which high S/N archival data are available for the HARPS high resolution spectrograph at the ESO 3.6m telescope. We perform a differential analysis of
A BCool magnetic snapshot survey of solar-type stars
We present the results of a major high-resolution spectropolarimetric BCool project magnetic survey of 170 solar-type stars. Surface magnetic fields were detected on 67 stars, with 21 classified as
The stellar metallicity distribution of disc galaxies and bulges in cosmological simulations
By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs).
A test for radial mixing using local star samples
Abstract We use samples of local main-sequence stars to show that the radial gradient of [Fe/H] in the thin disk of the Milky Way decreases with mean effective stellar temperature. We use the angular


Determination of stellar ages from isochrones: Bayesian estimation versus isochrone fitting
We present a new method, using Bayesian estimation, to determine stellar ages and their uncertainties from observational data and theoretical isochrones. The result for an individual star is obtained
Metallicities and activities of southern stars
Aims. We present the results from high-resolution spectroscopic measurements to determine metallicities and activities of bright stars in the southern hemisphere. Methods. We measured the iron
Spectroscopic parameters for 451 stars in the HARPS GTO planet search program - Stellar [Fe/H] and the frequency of exo-Neptunes
To understand the formation and evolution of solar-type stars in the solar neighborhood, we need to measure their stellar parameters to high accuracy. We present a catalogue of accurate stellar
Validation of the new Hipparcos reduction
Context. A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than magnitude Hp = 8 to be better, by up
The Geneva–Copenhagen Survey of the Solar Neighbourhood
Abstract We report on a new survey of metallicities, ages, and Galactic orbits for a complete, magnitude-limited, and kinematically unbiased all-sky sample of 16 682 nearby F- and G-dwarfs. Our ∼ 63
Empirical calibrations of the uvby, beta systems. II. The B-type stars.
Photoelectric photometric four-color and H..beta.. indices have been calibrated for A-type stars (stars with 2.890 >..beta..>2.720 and deltac/sub 1/<0.28 that are not B-type stars) in terms of
Y 2 Isochrones with an Improved Core Overshoot Treatment
Convective core overshoot affects stellar evolution rates and the dating of stellar populations. In this paper, we provide a patch to the Y2 isochrones with an improved treatment of convective core
