R. Michael Jennings & Eugene Chiang, 2021, accepted to MNRAS

Below are movies of simulations of fragments forming from gravitational instability in circumstellar discs. We use the code Athena to simulate self-gravitating flows in a 3D shearing box.

Density projections of our beta_0 = 10 fiducial run.

Density projections of our beta_0 = 20 high resolution run.

Density projections of our beta_0 = 10 high resolution run.

Density projections of our b_0 = 500 optically thin run.

Density projections of our b_0 = 600 optically thin run.
