Galactic metallicity distribution from open clusters
We have compiled two new Galactic open cluster catalogues. The first one has 119 objects with age, distance and metallicity data, while the second one has 144 objects with both absolute proper motion and radial velocity data, of which 45 clusters also with metallicity data available. An iron radial gradient of about −0.063±0.008 dex kpc−1 is obtained from our sample. By dividing clusters into a...
متن کاملDeriving the Metallicity Distribution Function of Galactic Systems
The chemical evolution of the Milky Way is investigated using a dual-phase metal-enriched infall model in which primordial gas fuels the earliest epoch of star formation, followed by the ongoing formation of stars from newly accreted gas. The latest metallicity distribution of local K-dwarfs is reproduced by this model, which allows the Galactic thin disk to form from slightly metal-enriched ga...
متن کاملThe radial metallicity gradient in the Galactic disk
The aim of this work is to estimate the radial metallicity gradient in the Galactic disk toward the anticenter direction. For that we use Strömgren photometric data which allow us to compute individual physical parameters through empirical calibrations. We detect that metallicity calibrations found in the literature present discontinuities between photometric regions. By this, in the present wo...
متن کاملLarge and small-scale structures of the local Galactic disc
An analytical model based on the maximum entropy approach is proposed to describe the eventual asymmetries of the velocity distribution, which are collected through its sample moments. If an extended set of moments is available, the current method provides a linear algorithm, associated with a Gramian system of equations, that leads to a fast and suitable estimation of the velocity distribution...
متن کاملOn the Galactic Disk Metallicity Distribution from Open Clusters I. New Catalogues and Abundance Gradient
In this paper we have compiled two new open cluster catalogues. In the first one, there are 119 objects with ages, distances and metallicities available, while in the second one, 144 objects have both absolute proper motion and radial velocity data, of which 45 clusters also with metallicity data available. Taking advantages of the large number of objects included in our sample, we present an i...
