The Stellar Disk Component: Distribution, Motions, Age and Stellar Composition

  • Conference paper
The Milky Way Galaxy

Part of the book series: International Astronomical Union ((IAUS,volume 106))

Abstract

The distribution of the stellar disk component is studied with particular emphasis on the properties of open clusters. A scale height of 80 pc is found for clusters younger than 109 years while the scale height is 200 pc for older clusters. A radial metallicity gradient in the disk is confirmed but there seem to be significant abundance variations apart from this. There are radial gradients in age as well as in linear diameter. Kinematically, there are a number of regions in the Milky Way with systematic radial velocity residuals.
