Modification of a proto-lunar disk by hydrodynamic escape of silicate vapor
Earth, Planets and Space volume 55, pages 53–57 (2003)
We have estimated a criterion for escape of silicate vapor from the disk formed by a giant impact. Escape from the disk affects the mass distribution and specific angular momentum of the disk. We applied the results to the disk formed by the Moon-forming impact. In the case of a hot (>6000 K) and highly vaporized (>63%) disk, the material outside of the Roche radius escapes. This indicates that the formation of the Moon is influenced by the thermal state of the disk just after the giant impact.
