Fig. 2


Sketches of the two possible geometries for the location of the maser disk inside the torus. Sizes are not to scale, and the sketches are just meant to display the different possible locations of the maser disk. a) The disk is part of the equatorial plane of the torus. b) The disk inflates in its outer part, giving rise to a geometrically thicker structure. The change from the inner part to the outer one is not abrupt and occurs with a gradual change in the dimensions and physical conditions of the clumps, encoded in the same density profile.
