A disk in the Galactic Center in the past ?
Emmi Meyer-Hofmeister, Friedrich Meyer, Bifang Liu
Abstract
We raise the question whether in the past a disk could have existed in our Galactic Center which has disappeared now. Our model for the interaction of a cool disk and a hot corona above (Liu et al. 2004) allows to estimate an upper limit for the mass that might have been present in a putative accretion disk after a last star forming event, but would now have evaporated by coronal action.
