Movies

All simulations are performed with the ORION code. The volume renderings are produced with yt.

STELLAR WINDS PRODUCING "Action at a Distance"

This movie shows the evolution of the magnetic field in turbulent gas with (top) and without stellar sources driving winds. The top panels show that magnetic waves are excited and propagate ahead of the bubble boundary. At later times, these panels show more gas structure at the locations outside the bubbles.

STAR FORMING CLOUD

This movie shows a volume rendering of gas density; it zooms from large to small scales and ends with a forming protostar. The size appears in the bottom right corner.

PROTOSTELLAR OUTFLOW: Density and Temperature

A volume rendering of both the gas density and temperature of a protostar launching an outflow. The temperature is computed using Hyperion. Box size is 800 AU.

TURBULENT ISOLATED CORE

Time evolution of the column density for 3 views of a simulated isolated dense core. A forming protostar launches an outflow that breaks out of the core. Box size is 0.26pc.

PROTOSTELLAR OUTFLOW VELOCITY

Volume rendering showing the time evolution of the gas velocity. The protostar location is marked with a cross. Box size is 0.3pc.
