Query: Modeling of Liquid Water on CM Meteorite Parent Bodies and Implications
  for Amino Acid Racemization   We have constructed an asteroid model with the intent of tracking the radial
and temporal dependence of temperature and composition throughout a 100-km
diameter CM-type parent body, with emphasis on constraining the temperature and
duration of a liquid water phase. We produce a non-uniform distribution where
liquid water persists longest and is hottest in the deepest zones and the
regolith never sees conditions appropriate to aqueous alteration. We apply the
model predictions of the liquid water characteristics to the evolution of amino
acids. IN some regions of the parent body, very little change occurs in the
amino acids, but for the majority of the asteroid, complete racemization or
even destruction occurs. We attempt to match our thermal model results with CM
meteorite observations, but thus far, our model does not produce scenarios that
are fully consistent with these observations.
