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 ∼ 63 000 new, accurate radial velocities for nearly 13 500 of the stars, combined with Hipparcos parallaxes and Tycho-2 proper motions, complete the kinematic data for 14 139 stars and allow us to identify most of the binary stars in the sample. Isochrone ages have been determined whenever reliable… 
Analysis of peculiarities of the stellar velocity field in the solar neighborhood
Based on a new version of the Hipparcos catalogue and an updated Geneva-Copenhagen survey of F and G dwarfs, we analyze the space velocity field of ≈17 000 single stars in the solar neighborhood. The
Dynamical evidence of the age-metallicity relation in the Milky Way disk
Aims. We studied the relationship between the average stellar abundance of several elements and the orbital evolution of stars in the neighbourhood of the Sun. Methods. We used both observational
Evolution of the velocity ellipsoids in the thin disk of the Galaxy and the radial migration of stars
Data from the revised Geneva-Copenhagen catalog are used to study the influence of radial migration of stars on the age dependences of parameters of the velocity ellipsoids for nearby stars in the
The RAVE survey: constraining the local Galactic escape speed
New constraints on the local escape speed of the Galaxy are reported, finding that the escape velocity lies within the range 498 <v(esc) <608 km s (-1) (90 per cent confidence), with a median likelihood of 544 km s(-1).
Vertical distribution of Galactic disk stars , IV. AMR and AVR from clump giants
We present the parameters of 891 stars, mostly clump giants, including atmospheric parameters, distances, absolute magnitudes, spatial velocities, galactic orbits and ages. One part of this sample
Nearby stars of the Galactic disc and halo – IV
The Milky Way Galaxy has an age of about 13 billion years. Solar-type stars evolve all the long way to the realm of degenerate objects on essentially this time-scale. This, as well as the particular
Solar Type Stars as Calibrators : A Photometric and Spectroscopic Study on the Atmospheric Properties of Late-type Stars
The relativley large spread in the derived metallicities ([Fe/H]) of M dwarfs shows that various approaches have not yet converged to consistency. The presence of strong molecular features, and
Kinematics and history of the solar neighbourhood revisited
We use proper motions and parallaxes from the new reduction of Hipparcos data and Geneva-Copenhagen radial velocities for a complete sample of ∼15 000 main-sequence and subgiant stars, and new Padova
Relationship between the velocity ellipsoids of galactic-disk stars and their ages and metallicities
The dependences of the velocity ellipsoids of F-G stars of the thin disk of the Galaxy on their ages and metallicities are analyzed based on the new version of the Geneva-Copenhagen Catalog. The age
The relations between the metallicity and orbital parameters of Galactic disk stars
The iron abundance gradient in the Galactic disk provides fundamental constraints on the chemical evolution of this important component of the Galaxy. However, there are still some arguments about


Local Stars as Tracers of Galactic Evolution
We describe the overall properties of a new catalogue of metallicities, ages, and galactic orbits for a large, complete sample of F and G dwarfs in the solar neighbourhood. Based on a
Local stellar kinematics from Hipparcos data
From the parallaxes and proper motions of a kinematically unbiased subsample of the Hipparcos Catalogue, it is re-determined as a function of colour the kinematics of main-sequence stars that spiral arms are responsible for the non-axisymmetry and that R0/Rd ≃ 3 to 3, where Rd is the scalelength of the disc.
The solar neighborhood age-metallicity relation - Does it exist?
We test the hypothesis that the spread in the age-metallicity plot of the solar neighborhood is due to a mixture of stars belonging to kinematically different sub-populations of the Galactic disk,
Velocity distribution of stars in the solar neighbourhood
A two-dimensional velocity distribution in the UV plane has been obtained for stars in the solar neighbourhood, using Hipparcos astrometry for over 4000 ‘survey’ stars with parallaxes greater than 10
Kinematics of the outer stellar halo
We test whether the simple model for the kinematics of the Galactic stellar halo (in particular the outer halo) proposed by Sommer-Larsen, Flynn & Christensen (SLFC) is physically realizable, by
The Distribution of Nearby Stars in Velocity Space Inferred from HIPPARCOS Data
The velocity distribution f(v) of nearby stars is estimated, via a maximum likelihood algorithm, from the positions and tangential velocities of a kinematically unbiased sample of 14,369 stars
An Investigation of the Relations Between Age, Chemical Composition and Parameters of Velocity Distribution Based on uvbyβ Photometry of F Stars within 100 Parsec
The basis of the investigation is the uvby and H(3 survey of A5 to GO stars brighter than visual magnitude 8.3 by E.H. Olsen. The calibration of the photo­ metric indices to yield effective
Proper Motion of the Compact, Nonthermal Radio Source in the Galactic Center, Sagittarius A*
Proper motions and radial velocities of luminous infrared stars in the Galactic center have provided strong evidence for a dark mass of 2.5 × 106 M☉ in the central 0.05 pc of the Galaxy. The leading

The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012. GAIA will provide
Chemical composition of 90 F and G disk dwarfs
High resolution, high S/N spectra have been obtained for a sample of 90 F and G main-sequence disk stars covering the metallicity range 1:0 < (Fe/H) < +0:1, and have been analysed in a parallel way
