Movie: Gas flows

This movie shows the face-on evolution of the gas in the rotating frame of the bar. The box is 10 kpc on a side, i.e., slightly larger than the corotation circle. The inclination of the stellar bar is 25 deg clockwise from top. The gas flow is asymmetric most of the time and remains time-dependent during the whole simulation.

These results come from a completely self-consistent hybrid particle-mesh and SPH N-body simulation of the Milky Way described in Fux (1999).
