Re: Significant exoplanet finding announcement on Monday

Cannot find anything on arXiv again tonight - where are the submissions? Also thinking that if sub stellar are given b designation when significantly > 13 Mj yet well below 80 Mj (ongoing fusion approx) how are they to be classified?

The HD 40307 et al. systems announced last June took several months for their papers to show up.

That's a really good question

I can't remember if it is COROT or SuperWASP that holds the record for longest time between press release and appearance of the discovery paper.

Surely COROT, which seems is going to announce the millennium discovery, the top-secret facts and then...hot jupiters as usual.

Except the one and only super-earth in tightest orbit.

In the original text-based table, four systems are listed as having a "curved drift", which may mean another planet: HD 44219, HD 148156, HIP 5158, and HD 104067.

Steinn Sigurðsson's take on this at Dynamics of Cats has some interesting musings about the implications of this for the planet-metallicity correlation.

Interesting read. Could it be that gas planets aren't actually preferentially formed around high-metallicity stars? Instead, could it be that high metallicity disks simply help to facilitate migration, leading to more easily detected planets?
