In this article the authors simulate the collapse of a magnetized, turbulent molecular cloud core to see if rotationally supported discs can form around central protostars.
Smoothed Particle Hydrodynamics (SPH) is one of the most commonly used techniques for simulating astrophysical fluids. This particular paper focuses on a regime of gas dynamics that is often neglected in astronomy: subsonic turbulence. Just as the air in the upper atmosphere exhibits random motions that can buffet an airplane cabin, the gas in interstellar space also exhibits random, turbulent motions.
