Using the data from the new WASP diagram (except for the 0.66 day period listed for WASP-9) and retaining the assumption that USD 25M has been spent in aggregate on ground-based transit searches, the 46 reported transits come out with the following valuations: [...] [...] Despite the difficulty in getting accurate quotes from the exchange, it’s interesting to see how the ten new planets stack up in the transit pricing formula.

Ignasi Ribas and two collaborators are reporting the “possible discovery” of a 4.8 Earth mass planet in an exterior 2:1 mean motion resonance with the transiting hot Neptune Gliese 436b. Planet four three six b is the well-known subject of great consternation, great scientific value, and many an oklo.org post. (For the chronological storyline, see: 1 (for background), 2, 3, 4, 5, 6, 7, 8, 9, and 10.) [...] [...] There’s a provocative paper up on the astro-ph today.

The system is so young that the protoplanetary disk is still there. Even more intriguing, there seems to be evidence of orbital clearing as the planet migrated inwards. abstract -- http://www.nature.com/nature/journal/v451/n7174/abs/nature06426.html Looks like Setiawan et al. hit a jackpot — a massive hot Jupiter in a 8-10 million years old system TW Hydrae.

I wonder how much the ranking would change if superjovians (which seem to be rather rare in short-period orbits) as well as low-mass planets get increased values.

I just have a related philosophical thought: - What is a scientific announcement? The somewhat vague definition of announcement from a Thesaurus is: "A message that is stated or declared; a communication (oral or written) setting forth particulars or facts etc" In science, the facts and particulars should be clearly spelled out. What if crucial and basic parameters are missing from the 'announcement', such as coordinates, period, identification? Maybe an announcement in science is something others can independently confirm? (or at least comment on, should the announcement be on a unique natural phenomena that happened only once)? I agree with Andy …
