Next: Biases Up: Contents Previous: Stars without Periods . Based on the data presented in Figure , I can suggest several conclusions about the evolution of young stars. The results of the Kolmogorov--Smirnov (KS) tests with the data presented here and those of Choi & Herbst (1996) on similar regions of the histogram indicate that there is something which holds stars near eight day periods. Stars in different regions also seem to share a similar mechanism which regulates the fast rotators. ...
