Moved to General Questions, it wasn't exactly 'news'-worthy.

Don't fret too much about it, planets are often reported here before they're reported there anyway. Years ago, before I found ArXiv, I would have panic attacks at such messages too, but now I'm not so dependent on exoplanet.eu for news and updates.

I don't think so, but surely 2009 (especially December month) has been a hot period for exoplanets.

EPE is a well-done site but not always is up to date.

For example there's still a paper available at California Carnegie site (that usually is seldom up to date) claiming 5 new planets that hasn't yet been posted at EPE. But notes for individual planets are available...

Back to 84 now (did someone claim to have discovered a planet by astrometry or something?). I doubt the full 100 is going to happen this year somehow.

Astrometry seems made of fail, indeed

However simulating with Systemic console, RV sets hint me a similar signal for a Neptune-sized planet. Probably spurious?

Probably, the RV data for this star isn't very accurate, considering how dim it is.

If we take year of discovery as the year in wich the paper is released por publication , then no , we will not reach 100 , but if we take the year of discovery as the year where the team reach the conclusion that the data fits a planet , and start writing down the article , i would vote on 120+ planets.

I take the second stance and so my vote for a yes Smile

If we take the first option (year of publication) , then 2010 will have more than 200 planets on the roll count Smile

ciceron,

I agree assuming that RV confirmation programs for transit candidates can be sustained at a high rate (higher than now). Otherwise, exoplanet announcements in 2010 will be greatly reduced.

Think only HATnet discovery around 100 planets...

http://arxiv.org/abs/0907.2924
To address these topics we use data from HATNet to conduct a variability survey of K and M dwarfs. The ongoing HATNet project is a wide-field search for transiting extrasolar planets (TEPs) orbiting relatively bright stars. The project employs a network of 7 robotic telescopes (4 in Arizona at Fred Lawrence Whipple Observatory, 2 in Hawaii on the roof of the Sub-Millimeter Array at Mauna Kea Observatory, and 1 in Israel at Wise Observatory; the latter is referred to as WHAT, see Shporer et al. 2009) which have been used to obtain some  700, 000 images covering approximately 10% of the sky. The survey has generated light curves or approximately 2.5 million stars, from which  900 candidate TEPs have been identified. To date, the survey has announced the discovery of 12 TEPs, including HATP-11b (Bakos et al. 2009), a Super-Neptune (0.08 MJ ) planet that is the smallest found so far by a ground-based transit survey.

The first exoplanets were found in 1995 by swiss astronomers Major/Queloz! Everything else is unscientific. If you want to read the true story look at: [link removed]. As always: success has many fathers, failure none!

Shameless advertisement of pseudo-scientific theories removed. -- Sirius Alpha
