Final Assembly of Earth-Like Planets
April 16, 2007 / Posted by: Shige Abe
NAI Postdoctoral Fellow Sean Raymond leads a team of authors from NAI’s University of Colorado, Boulder, and University of Arizona Teams, and Virtual Planetary Laboratory and University of Washington Alumni Teams in a new publication in Astrobiology. They present analysis of water delivery and planetary habitability in 5 high-resolution simulations forming 15 terrestrial planets. Their results outline a new model for water delivery to terrestrial planets in dynamically calm systems, which may be very common in the Galaxy.
