|The present-day state of the Milky Way disk can tell us much about the
history of our Galaxy and provide insights into its formation.
We have constructed a high-precision catalogue of disk
stars using data from the Sloan Digital Sky Survey (SDSS) and use these
stars to probe the heating history as well as investigating the
detailed phase-space distribution. We also show how this sample can be
used to probe the global properties of the Milky Way disk, employing
the Jeans equations to provide a simple model of the potential close
to the disk. Our model is in excellent agreement with others in the
literature and provides an indication that the disk, rather than the halo,
dominates the circular speed at the solar neighborhood.
The work presented in these proceedings has been published as
“Slicing and dicing the Milky Way disc in SDSS” (Smith et al. 2012).
