For a topic like this, it's better to wait until the paper has passed
through the review process, since parts of the paper (maybe large parts)
are likely to change.

That entire Extrasolar Planets website (http://exoplanet.eu) is all
Jean Schneider's work; a "labor-of-love",  as it were. Amazing, hm?

BTW: A news item that some may not be aware of, is that the Corot mission,
the first dedicated extrasolar Earthlike planet space mission, has
its launch date pushed from October to 18 December:
