Abstract
This study explores how cosmic rays created in star forming environments interact with the accretion disk of gas and dust that surrounds the star. MATLAB is used to simulate the propagation and energy deposition of cosmic rays injected into idealized models of the accretion disk and is directly tied to how quickly cosmic rays lose their energy as they ionize the gas in the disk. While not considered in our work, the results have bearing on the degree to which the disk is ionized, which affects both the accretion rate of gas onto the forming star and the chemistry that drives the formation of planets.
