Critical study of the distribution of rotational velocities of Be stars; II: Differential rotation and some hidden effects interfering with the interpretation of the Vsin i parameter

J. Zorec, Y. Frémat, A. Domiciano de Souza +9

We assume that stars may undergo surface differential rotation to study its impact on the interpretation of $V\sin i$ and on the observed distribution $\Phi (u)$ of ratios of true ro…
