Relations between He I and circumstellar Fe II and Mg II

We have studied, in the photographic and UV regions, stars presenting forbidden components of He I in absorption. With the aid of theoretical models available in the literature, we have concluded that dissipation of mechanical energy is more important in equatorial regions. We have also observed tha...
