One of the key problems in planetary formation research is to determine the properties and dynamics of protoplaneary accretion disks where all planetary formation occurs. An increasingly useful probe into these systems is near infrared spectroscopy of ro-vibrational CO emission. The goal of the study is to develop techniques that utilize synthetic spectra generated via a modeling algorithm fitted to actual spectral data gathered from protoplanetary systems to determine specific properties of the system. We currently have a working algorithm which generates synthetic spectra based upon a number of degenerate parameters. In order to generate the best fit given the degenerate nature of the parameters we are developing a Monte Carlo algorithm that will determine local as well as absolute minima in a ten dimensional surface plot. Once this is completed we will utilize two CONDOR clusters to generate fits for hundreds of known protoplanetary systems.The result will be the largest, most descriptive database of protoplanetary systems, an essential tool for planetary and stellar researchers. This project was funded by a partnership between the National Science Foundation (NSF AST-0552798), Research Experiences for Undergraduates (REU), and the Department of Defense (DoD) ASSURE (Awards to Stimulate and Support Undergraduate Research Experiences) programs.
