Candidates and Upgrades

Hello everyone, graduate student John here. The time has finally arrived and we have the first batch of candidates up for you. To top it off, we have also managed some interface updates which should make marking transits faster and easier (yeah, Stuart!).

First, the candidates. I have a blog post coming out shortly which will explain how we made our selections so for now I will just give you the results. If you roll on over to the Candidates page, you will find that there are 132 new stars. That breaks down into 90 new potential planet candidates and 42 potential eclipsing binaries. We are still hard at work modeling these systems, so don’t have much more information than that it made the cut. We thought you would rather see them now and we will add the periods and radii as we do the fits.

Along with the new candidates, you can now see stars which you viewed which are possible planet or eclipsing binary candidates.

Which brings us to the other interface updates: transit marking. Now when you want to mark a transit on a star, you can simply drag a box around all of the points in the transit. Once drawn, the boxes work exactly as they did before. This should help us get more precise transit center information to more easily track down interesting candidates. Another perk is that clicking on any of the transit boxes will zoom you to that location on the plot.

Bring on the new data!

    Now, either I should be extremely excited to be among the “discoverers”, or I should be ashamed that I marked over a hunderd of potential transits, collected a few dozens and got just one right.

    Can you tell us the ratio of the number of stars where users marked a transit feature to the number of stars where transit candidates were indeed confirmed, or is it too early/it could bias the ongoing experiment?

    The new way to mark transits is really more practical and helps a lot, thanks PH team! I didn’t have noted about the zoom on transits boxes, very cool, I’m going to PH site to test it now.

    And I’m so happy because I found two potential EB!!!! Happy, happy, happy! Yupi!And anxious for the new data.

    Remember that if you marked a transit on a star, 4 other people also had to mark one for us to look at it this time around. In addition, we also excluded any stars which have already been published by someone else in this first set.

    We will be publishing some statistics much like what you are asking for using published stars and the synthetics, but we still have some work to do before those numbers are available.

    I think we will see the candidate numbers go up as we improve our process and the new data start rolling in.

    This alone explains a lot, thanks anyway 🙂

  6. HeadAroundU says :

    I have classified 5166 stars. 776 stars marked with transit, 407 favorited and 64 in my first collection.

    I have 5 planet candidates and 3 eclipsing binary candidates.

  7. JoeFly says :

    Classified 1600 stars. I have 1 planet candidate and 1 eclipsing binary candidate 🙂

  8. mcdof says :

    I classified ~1200 stars, and spoted 3 planet candidates and no EB..1/400 seems fine!!!

  9. douglas says :

    It’s a shame that 5 people have to mark a transit before it’s promoted, especially since i go through the data meticulously in 5 day checks, searching for anything that looks like it could be a transit at all, the smallest dent, or the light falling in a line, i imagine that most don’t check as vigorously. I recon I detect about half the simulated transits.

    So how about some testing to make some searchers more qualified than others?

    808 stars classified, 2 binary and 2 planets.. good
