Density slices through the center of the domain at the birth of the protostar (t = 0, panel a) and roughly 2 months later (t ≈ 59 days, panel b). The swirly patterns are line integral convolution (LIC) visualizations of the velocity vector field, which display prominent eddies inside the newly formed protostar. Over the span of ≈2 months, the protostar has grown in radius by a factor ≈2.8.
