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...

| Sumario: | 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 that ionized Fe and Mg present higher expansion velocities at the polar regions. |
