A Stable Hypermassive Neutron Star:
T/W ~ 0.23


We choose to evolve the differentially rotating configuration indicated by the white dot and find that it is stable. This hypermassive star has a mass that is considerably larger than the maximum nonrotating or uniformly rotating mass.

This animation shows the differentially rotating surface of a stable hypermassive neutron star.

Scene 3: Density profile of Stable Star

indicates the central density, while indicates the maximum density. The two values do not coincide for this model.

As time evolves, the star remains stable, and its density profile is largely unchanged.
