is reporting that Corot has found its first planet. I can't find an arxiv paper about this, or even a press release, but there are many here better at squirreling out data releases than me. 1.3Mj, 1.8Rj so it's a very inflated planet, 1.5-day orbit around a 'star quite similar to the Sun' might account for that. In the Monoceros field (Corot is now pointing at the Scutum/Aquila field). |

I get the same result, JR.
A good question would be "how many transits do they need to see to confirm a discovery?" On the Kepler site, they say they'll only need one for Jovian planets (although obviously you need two to get the orbital period), but that for Earth-sized planets, they want to see three transits. If COROT switches targets every few months, that'd mean it really wouldn't spot any Terrestrial planets with periods longer than a few weeks. That'd still be very interesting, but makes it seem unlikly they'll find anything that could fairly be described as "another Earth." --Greg |
