Planets form within the dusty circumstellar disks around young stars. Samples of the solid material composing our own primitive disk are found in meteorites and interplanetary dust particles. Using the powerful technique of mid-infrared spectroscopy via IRS on board Spitzer we will ascertain the composition of the material existing within the disks around young stars in several southern star forming regions. We will study a range of disks of varying ages around embedded, T Tauri, Herbig Ae/Be and Vega-type stars. In so doing we will determine how the dust composition evolves with time and/or environment, and what physical processes affect it, in order to better understand how our own solar system formed.
