I'd guess it's going to be something along the lines of a confirmed multi-transit system or a confirmed case of transit variations. "Exotics" like circumbinary planets or exomoons would be interesting but I somehow doubt it...

Exomoon?? It would be amazing to discover such body,in my opinion such discovery will not be earlier than 2012

Сircumbinary planets very probable.

Unless I'm in a time warp or can't convert time zones, not for another 1 hour and 8 minutes or so.

It's I'm just confused by time zones. Don't know if referred to Europe or USA.
But you gave me a useful reference so, let's wait Wink

Well it is up on the front page of the NASA website...

Two transiting giant planets around the same star, unconfirmed inner transiting super-Earth.

So multiple transiting planets AND detected transit timing variations. Nice.

But in general have been disappointing. Probably the confirmation process is very difficult.
Even in such a high-priority system was not successful confirm yet to the super-earth (with a period of only 1.5 days).

So far the FOP has obtained images of over 400 Kepler stars. So far, many hundreds of images and over 700 spectra have already been taken of the Kepler planet candidates.

Perhaps 700 of these spectra, most reconnaissance (the first 1-2 spectra). Therefore, very few planets will be announced in 2010.

The error in measuring the mass of only 0.013 mass of Jupiter. Strange that it was not enough to determine the mass of the inner planet.

it seems to be 2 transiting saturns/jupites and a potential 1.5x hot super earth...

In general, the data Kepler for the first month already have at least 2 three-planetary candidate. Nice.

A post from the Centauri-dreams blog reports the system is in resonance.

Received for publication 28 July 2010. Accepted for publication 19 August 2010.

Hence, these results were obtained more than 1 month ago? Then, probably a mass of third planet can already identify.

I think they did but maybe are other reason why they wait to confirm it another body in the system??However I am very disappointed that only 2 planets announced.I expected something more than saturn type bodies

I don't get why this is regarded as so disappointing. This discovery should allow precise determination of the parameters of a resonant extrasolar system. Especially with the potential super-Earth in there, I'm going to guess this is going to be a valuable data point in the comparison of the mass-radius relationship at the same stellar metallicity.

The nature of missions like Kepler means that there are always going to be far more unconfirmed candidates (KOI nnn.pp) than confirmed planets (Kepler-nn). Expecting hundreds of confirmed planets is unreasonable.

Indeed, this is a great discovery. I think the reason people are dissapointed is that they allow their hopes and expectations to be inflated into the realm of "unrealistic" by sensationalist reportings. "Kepler, the spacecraft built to look for Earths, to announce big news today" instead of "Kepler team to announce interesting planetary system find."

Here's a paper on ArXiv.

Also, wrt this being not disappointing, isn't this first case of TTVs?

Supercool discovery for me!
