Conference paper


We discuss a simple model for the origin of the coronal and mass loss dividing lines which separate late-type giants and supergiants with and without X-ray emitting corona, and with and without significant mass loss. The basic physical effects we appeal to are magnetic confinement for hot coronal material and large reflection efficiency for Alfvén waves in the cool exponential atmospheres.
