The radial profiles of the Keto et al. (2015) model physical parameters are plotted. The black solid line represents the number density of molecular hydrogen, the blue dashed line the gas temperature, and the orange dash-dotted line the velocity profile of the Keto et al. (2015) physical model. In order to display the various parameters in a single plot, the base 10 logarithm of the number density of molecular hydrogen, the temperature divided by 3, and the velocity scaled by −40 are shown.
