Abstract: 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).
