Distance Dependence in the Solar Neighborhood Age-Metallicity Relation

  title={Distance Dependence in the Solar Neighborhood Age-Metallicity Relation},
  author={D. Garnett and H. Kobulnicky},
  journal={The Astrophysical Journal},
The age-metallicity relation for F and G dwarf stars in the solar neighborhood, based on the stellar metallicity data of Edvardsson et al., shows an apparent scatter that is larger than expected considering the uncertainties in metallicities and ages. A number of theoretical models have been put forward to explain the large scatter. However, we present evidence, based on the Edvardsson et al. data, along with Hipparcos parallaxes and new age estimates, that the scatter in the age-metallicity… Expand

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,Expand
Information from the Kinematics of F and G Stars in the Solar Neighborhood
We have calculated the orbital parameters for 90 stars in Chen et al. and updated the kinematic data for stars in Edvardsson et al. by using the accurate Hipparcos parallaxes and proper motions, andExpand
K dwarfs and the chemical evolution of the Solar cylinder
K dwarfs have lifetimes older than the present age of the Galactic disc, and are thus ideal stars for investigating the chemical evolution of the disc. We have developed several photometricExpand
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 aboutExpand
A revision of the solar neighbourhood metallicity distribution
We present a revised metallicity distribution of dwarfs in the solar neighbourhood. This distribution is centred on solar metallicity. We show that previous metallicity distributions, selected on theExpand
The Stellar Populations in the Outer Regions of M33. III. Star Formation History
We present a detailed analysis of the star formation history (SFH) of three fields in M33 located approximately four to six visual scale lengths from its nucleus. These fields were imaged with theExpand
Revisiting two local constraints of the Galactic chemical evolution
I review the uncertainties in two observational local constraints of the Galactic disc chemical evolution: the metallicity distribution of long-lived dwarfs and the age–metallicity relation.Expand
Metallicity-dependent signatures in the Kepler planets
Using data from the California-Kepler-Survey (CKS) we study trends in planetary properties with host star metallicity for close-in planets. By incorporating knowledge of the properties of theExpand
Isochrone ages for field dwarfs: method and application to the age–metallicity relation
A new method is presented to compute age estimates from theoretical isochrones using temperature, luminosity and metallicity data for individual stars. Based on Bayesian probability theory, thisExpand
Simultaneous modelling of the stellar halo and globular cluster system of NGC 5128
An important test for models of galaxy formation lies in the metallicity distribution functions (MDFs) of spheroid stars and their globular clusters (GCs). We have compared the MDFs obtained fromExpand


The chemical evolution of the solar neighborhood. II - The age-metallicity relation and the history of star formation in the galactic disk
The age-metallicty relation for the disk in the neighborhood of the Sun is derived from four-color and H..beta.. photometry of a large sample of southern F dwarfs, analyzed in combination withExpand
Some Revised Observational Constraints on the Formation and Evolution of the Galactic Disk
A set of 76 open clusters with abundances based upon DDO photometry and/or moderate dispersion spectroscopy has been transformed to a common [Fe/H] scale and used to study the local structure andExpand
Elemental Abundance Variations and Chemical Enrichment from Massive Stars in Starbursts. I. NGC 4214
This spectroscopic study of NGC 4214 is part of a project to determine the extent to which the winds and supernovae from massive stars contribute to the short-term, localized chemical enrichment ofExpand
A Stochastic Approach to Chemical Evolution
Observations of elemental abundances in the Galaxy have repeatedly shown an intrinsic scatter as a function of time and metallicity. The standard approach to chemical evolution does not attempt toExpand
