(a) Decay of rotating Bose star in the model with purely gravitational interactions

(a) Decay of rotating Bose star in the model with purely gravitational interactions (l=1 and lambda=0); see arXiv:. Rotating Bose star is a gravitationally self-bound drop of the Bose-Einstein condensate with nonzero angular momentum. It has a donut form, and its horizontal (z=0) section is a ring. The movie shows evolution of the star density (color) at z=0. Initially, the Bose star is stationary. But as the time goes on, it splits into two spherical objects rotating around the mutual center of mass. Then one of the objects gets tidally disrupted, while the other persists. The final configuration includes a non–spinning star and a cloud of diffuse particles rotating around the mutual center.
