The purpose of this work is to resume investigation of Galactic thin disk dating using nucleocosmochronology with Th/Eu stellar abundance ratios, a theme absent from the literature since 1990. A stellar sample of 20 disk dwarfs/subgiants of F5 to G8 spectral types with −0.8 ≤ (Fe/H) ≤ +0.3 was selected. In stars with such spectral types and luminosity classes, spectral synthesis techniques must be employed if we wish to achieve acceptably accurate results. An homogeneous, self-consistent set of… 

The age of the Galactic thin disk from Th/Eu nucleocosmochronology - II. Chronological analysis

The purpose of this work is to resume investigation of Galactic thin disk dating using nucleocosmochronology with Th/Eu stellar abundance ratios, a theme absent from the literature since 1990.

The age of the Galactic thin disk from Th/Eu nucleocosmochronology: extended sample

We report the determination of the age of the Galactic thin disk by means of Th/Eu nucleocosmochronology. This method is only weakly dependent on stellar evolutions models, therefore allowing an

Abundances of neutron-capture elements in stars of the Galactic disk substructures

Aims. The aim of this work is to present and discuss the observations of the iron peak (Fe, Ni) and neutron-capture element (Y, Zr, Ba, La, Ce, Nd, Sm, and Eu) abundances for 276 FGK dwarfs, located

Basic physical parameters of a selected sample of evolved stars

We present the detailed spectroscopic analysis of 72 evolved stars, which were previously studied for accurate radial velocity variations. Using one Hyades giant and another well studied star as the

Abundances of Mn, Co and Eu in a sample of 20 F–G disk stars: the influence of hyperfine structure splitting

We present Mn, Co and Eu abundances for a sample of 20 disk F and G dwarfs and subgiants with metallicities in the range −0.8 ≤ [Fe/H] ≤ +0.3. We investigate the influence of hyperfine structure

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

The Alpha Centauri Binary System: Atmospheric Parameters and Element Abundances

Context. The α  Centauri binary system, owing to its duplicity, proximity and brightness, and its components' likeness to the Sun, is a fundamental calibrating object for the theory of stellar

Astrobiologically interesting stars within 10 parsecs of the sun.

It is shown that approximately 7% of the nearby stars are optimally interesting targets for exobiology, after eliminating multiple stars, young, chromospherically active, hard x-ray- emitting stars, and low metallicity objects.

Europium as a lodestar: diagnosis of radiogenic heat production in terrestrial exoplanets

Context. Long-lived radioactive nuclides, such as 40K, 232Th, 235U, and 238U, contribute to persistent heat production in the mantle of terrestrial-type planets. As refractory elements, the

ACCURATE ATMOSPHERIC PARAMETERS AT MODERATE RESOLUTION USING SPECTRAL INDICES: PRELIMINARY APPLICATION TO THE MARVELS SURVEY

Studies of Galactic chemical, and dynamical evolution in the solar neighborhood depend on the availability of precise atmospheric parameters (effective temperature Teff, metallicity [Fe/H], and

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

Contamination of the Th II line and the age of the Galaxy

THE age of the Galaxy may be estimated from observations of the ratio of stellar abundances of thorium, which has only one long-lived isotope with a half-life comparable to the suspected age of the

Lithium Abundances in Solar-Type Stars 1

We report Li abundances from the λ6707 line for 19 nearby dwarf and subgiant solar-type stars. The unevolved stars in this sample present high (> 2.00) Li abundances. We found a few cases of subgiant

High-resolution CCD spectra of stars in globular clusters. VII : Abundances of 16 elements in 47 Tuc, M4, and M22

We have derived elemental abundances from high-resolution CCD echelle spectra of a selection of giant stars in the globular clusters 47 Tuc, M4, and M22. Elements determined include the α elements

An abundance analysis of Alpha Centauri A

A differential abundance analysis between the sun and Alpha Cen A has been carried out. Over 500 lines of 26 elements have been measured in very high signal-to-noise ratio spectra of both objects.

Europium abundances in F and G disk dwarfs

Europium abundances for 74 F and G dwarf stars of the galactic disk have been determined from the 4129.7 A Eu II line. The stars were selected from the sample of Edvardsson et al. (1993) and [Eu/Fe]

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.
