Seminar by Sabrina Appel, Rutgers
Gravity, turbulence, magnetic fields, and stellar feedback all play important roles in star formation. The impact of these physical processes is reflected in the distribution and dynamics of the gas in star forming regions and understanding the impact of each of these processes on the gas is important for understanding both observations and simulations of star formation. In this talk, I will investigate the connection between cloud-scale processes and the gas dynamics using 3D magnetohydrodynamical simulations of star-forming regions. We explore how the gas dynamics varies with the inclusion of various physical processes and compare the gas dynamics to the features of the density PDF. We find that protostellar feedback produces rapidly expanding and compressing gas at low densities. Finally, we compare the gas dynamics as a function of density to the star formation rate.
