Kepler News and Results

In fact, they have found every 1 in 6 stars hosts at least an Earth-sized planet in a close orbit (like the distance of planet Mercury or closer). They said that in the January AAS conference. You can extrapolate this to longer periods.

So it' s a question of time they have new data and process the existant data, to find this earth analogs.

I thing that rumour is a misunderstanding.

Ah, but can you actually do that?

As my university professors liked to point out, extrapolation is dangerous...

Well...strictly speaking... you are right.

But i was thinking they have more data to compare with, and giant planets in longer periods, and every time they have processed more data more little planets appeared.

I think it was a misunderstanding, because they said they can' t find yet an earth analog (not enough data). But they have already found earth sized planets and bigger longer period planets... So It' s only a question of time to find these earth twins.

SOPHIE velocimetry of Kepler transit candidates. VIII. KOI-205 b: a brown-dwarf companion to a K-type dwarf
http://arxiv.org/abs/1302.2628

40 Jupiter mass brown dwarf in a 12-day orbit.

It's seems that KOI-245(now Kepler-37) have 3 confirmed and 1 candidate planet.the forth candidate has 0.43 Earth radii in 50.1 days orbit

Don't know how much there will be from this conference, feel free to split it out of this thread...

Anybody knows the distance of star KOI 1422? I haven' t found this data it in any place.

Many thanks.

Thanks. Lightyears or parsecs?

Please start citing sources. It's what separates a credible post from a YouTube comment.

On arxiv low stellar obliquities in compact planetary system.I have some strange problems with links sorry

You may as well cite "the internet."
Just start posting links specifically to where you find information. Otherwise there is no reason for any of us to take you seriously.

Kepler-13b finally appears?

Radius = 2.027 Rj

????
What kind of problem?

You could even just paste the URL into the post directly if needs be. (I am starting to actually prefer this method because it looks like the forum doesn't make external links available to users who are not logged in.)

I have tommi59's same problem. The Kepler webpage cannot be viewed.

What is the problem? I still have no idea what is meant by "some strange problems with links"...

Forget about it. I wonder,planet hunters published paper where one system KOI 435 has 6 potential planet I did not find any more from this likely interesting star no comments,opinion from kepler team?

@tommi59:

Can you paste the URL into your post? Even if it doesn't link it properly it is just a small amount of effort to copy this into the address bar of a web browser

Even the title would be an improvement of your vague references to some random paper somewhere.

Otherwise you are just sending everyone out on internet searches to figure out what you are talking about.

Thanks edasich

Some studies indicate that fluffy super earths are likely H2O free, just surrounded by an atmosphere of H/He:
