Title: |
The Age-Velocity-Metallicity Relation in the Nearby Disk |
|
Project Description: |
As the galactic disk evolves, it becomes chemically enriched and the
random velocities of its stars increase as they interact with spiral arms
and molecular clouds. The relation between age, velocity and metallicity
is the basis for our understanding of the evolution of galactic disks,
but is currently not well determined. We are undertaking a large
observational program of about 1000 stars to determine the definitive relation. |
