Abstract/Description: Star formation holds many answers to how the universe has evolved and how we came into existence. A big question in star formation theory centers around the role of magnetic fields and how strong they must be in the cloud to coincide with the observed star formation rate. However, measuring the magnetic fields in molecular clouds can be difficult due to the clouds being cold and optically thick in the optical band. Turbulence increases the difficulty by creating chaotic conditions within the clouds. One method of determining determining these characteristics is by simulating collapsing molecular gas clouds using the principles of self-gravitation, magnetic fields, and turbulence, the main components of star formation. Data analysis of Enzo simulation data was done to help determine what the relative strength and angular orientation of magnetic fields around pre-stellar cores were relative to the global cloud. For our trans- and super-Alfvénic simulations, the preliminary results indicate that magnetic field orientations of prestellar cores are positively correlated with the mean magnetic field direction of the molecular cloud. This is similar to trends found in both observations and a sub-Alfvénic simulation.
