- Abstract
We present results of collision simulations pertaining to water loss covering body masses ranging from a small planetary embryo to the mass of Earth. We find that for most realistic combinations of object masses, collision velocities, and impact angles a considerable amount of water is lost, which may significantly change the water inventory of formed terrestrial planets. Also, there is indication that beyond the 'usual' parameters characterizing a collision (velocity expressed in units of the mutual escape velocity and impact angle), water loss depends on factors like absolute mass, the projectile-target mass ratio, and to a certain extent the water distribution inside the objects.
