Star systems arise from large clouds of dust and gas that collapse and form disks. The dynamics of this process are complicated because temperature and density are related to each other in nonlinear ways during the collapse. This study simulates the process of a cloud forming a disk under different kinds of relationships between temperature and density, helping astronomers better understand this complicated process.
