ON THE VERTICAL STRUCTURE OF THE PROTOLUNAR DISK

The vertical structure of a post-impact, pre-lunar disk is examined. We adopt the equations introduced by Thompson & Stevenson for a silicate disk in two-phase equilibrium (vapor plus liquid) and derive an analytical solution to the system. This largely reproduces their low-gas mass fraction, x
