Updated Planet Candidates List and Q3 data

Hi all,

We’ve just updated the Candidates List to reflect what we’ve learned from Q1 and from a preliminary look through the Q2 data so far. Some candidates from Q1 have survived, others have not.  Each of these candidates looks promising to us and not on the  list of known  candidates released by the Kepler team.  These are possible planet candidates, that is, as far as we can tell, they look good and we think are not eclipsing binaries or false positives. But this doesn’t necessarily mean that these stars have planets. A minimum of three separate observed transits are needed as well as follow-up observations. From our first paper, you can see that after checking through everything only two of the top 10 we looked at turned out to be good. Many on the list might not turn out to be real planet transits,  but their appearance on our list means we think we’re on the right track. We will continue to follow-up and vet these candidates with observations from the Keck telescopes and other checks to try and rule out possible false positives.

We’re also keeping track of discovery credit. The names of those lucky hunters who are in line to make discoveries are listed on the candidates page as well. We have a full record in our database of what everyone did. Additionally, some of our candidates came from light curves that were highlighted in Talk, and we will be giving credit to those users who helped alert our attention to those light curves (we plan to have their names added soon on the Candidates List).

In other news, the Kepler team announced that the next public release of data has been moved up from June 2012 to yesterday . Quarter 3 is an extra 90 days of observations, nearly doubling the time baseline we have available for all the Kepler stars – meaning you can find even longer period planets hidden in the data! With the addition of Q3, we now have 210 days worth of Kepler data for ~150,000 stars. The team is hard at work making preparations for the new data, which included assembling the new candidates list. In the mean time, there’s still lots of Quarter 2 data left to search through, and the science team is continuing to search for transits in the Quarter 2 data with your classifications and Talk posts.

We are currently downloading the Q3 data, and Meg  is heading out to the folks at the  Adler Planetarium in Chicago early next week to help  check out the new data and  help plan the Q3 upload with our amazing Zooniverse developers who keep the Planet Hunters  site going. Our goal is to get the data served to you as quickly as possible with minimal interruptions to the site. We’ll keep you posted on the progress of the Q3 upload. So stay tuned!And thanks for all the clicks!

    Thank you for the update. I think I am seeing duplicates on the Candidates List. I have counted 36 in total, but minus the duplicates, there is only 21 left. It is like page 2 is the reverse of page 1. Something wrong with my display?
    The following are the duplicates:

    10002911
    10007403
    10022763
    10034677
    10037683
    10038553
    10044177
    10053596
    10063470
    10069370
    10069425
    10077908
    10079981
    10087373
    10092503

    Hi everybody … what a hard suspense to see if our planet candidates are false positive or not ; I agree with Lily on “your stars” planet candidates, there are also duplicates candidates : for my example, those are :

    10063470
    10069370

    In another note, what is the future of our EB candidates ? Will there be a scientific publication on the subject ? Thanks

  4. Meg says :

    Thanks – must be some small bug – we’ll fix that – thanks for spotting

    We’ll have a blog post detailing more about EBs soon hopefully
    Cheers,
    ~Meg

    Weren’t any of the duplicates possible multiplanet systems? I have another problem, when I click on a “planet candidate” the source page says “We have discovered that this star may be part of an eclipsing binary of period” … Huh?
