One for the world-builders:
The formation and habitability of terrestrial planets in the presence of close-in giant planets

Thanks.
That list contains two papers from a series of three by Barnes & Raymond, entitled Predicting planets in known extra-solar planetary systems ... One deals with test particles and the other with terrestrial planets. If like me you wondered what the missing paper was about, it discusses Saturn-mass objects, and it's at:
http://arxiv.org/PS_cache/astro-ph/pdf/0404/0404211.pdf

These papers seem to show that terrestrial planets might likely typically have much more water than Earth. So much so, that oceans tens of kilometres deep and no continents might be the norm. Could this be another factor in solving the Fermi paradox?

maybe...
