P2 Pi Y Pi r Pi i 5 mr

where P\ and P2 are the rotation periods before and after the collapse. The mass of the cloud is

Solving for the radius we get R = 3 x 1013 m. The rotation period after the collapse is

This is several orders of magnitude shorter than the actual period. Somehow the star has to get rid of most of its angular momentum during the process.
