May 5, 2015: ExoFOP-K2 is a web site designed to optimize resources and facilitate collaboration in follow-up studies of K2 targets. It serves as a repository for community-gathered follow-up data and is supported by Exoplanet Archive infrastructure.

In addition to continuing to support Kepler via the original CFOP website, this new service includes the K2 targets, and will eventually be expanded to support future missions.

The site is open to the entire community and currently contains magnitudes, finding charts, and nearby source lists for the targets from Campaigns 0-4 and the engineering campaign. A new feature allows users to designate possible planetary candidates, false positives and eclipsing binaries. ExoFOP-K2 will allow detailed searches of K2 targets similar to the CFOP search pages.

All content can be viewed and downloaded without logging in. A username and password are only required if you wish to upload data, notes, or files. Your existing CFOP user name and password will work on ExoFOP-K2.

May 4, 2015: The archive now hosts the first public release of KELT data, consisting of roughly 300,000 light curves in fields N02 and N04. Explore the data with the KELT search interface, read the documentation, or download the data in bulk by clicking the KELT tab in the Transit Surveys section of our home page.

April 30, 2015: Kepler-432 c has been added this week, as well as updated parameters for 14 planets: Kepler-432 b, PSR B1257+12 b, c & d, PSR B1620-26 b, HD 28185 b, HD 213240 b, HD 130322 b, HD 160691 b, HD 27442 b, HD 134987 b, HD 13445 b, HD 75289 b and HD 17051 b. See the Overview pages or go the Confirmed Planets interactive table.

We have 27 additional time series for MOA-bin-1L b, MOA 2009-BLG-319L b, and MOA 2011-BLG-293L b. Access the data through the planets' Overview pages.

April 23, 2015: This week we have one new planet, HD 100546 b, as well as additional parameters for 11 planets: 70 Vir b (new default), WASP-2 b, WASP-4b, WASP-5b, WASP-52 b, KELT-1 b, CoRoT-2 b, XO-2 b, TrES-1 b, HD 189733 b and GJ 436 b. See their Overview pages or go the Confirmed Planets interactive table.

Attention near-Earth Hunters: The archive has new Planet Detection Metrics (Window Function and One-sigma Depth Function) that were produced by the Transiting Planet Search (TPS) algorithm in the Kepler pipeline. These data can be used to characterize the detections of transits by the pipeline. Download the files in bulk or access them from an object's Overview page, and read the documentation.

April 16, 2015: This week we announce a new tool, new API keywords and new planets!

April 1, 2015: Today we have a few updates to report:

  • We've added five radial velocity HD planets, as well as new default parameters for three imaging planets: 1RXS J160929.1-210524 b, HIP 78530 b, and GSC 06214-00210 b, as well as defaults for Kepler-79 b, c, d and e. The HD planets are: HD 1605 b & c, HD 1666 b, and HD 67087 b & c. See their Overview pages or go to the Confirmed Planets interactive table.

  • We've added the Kepler Q1-17 DR 24 KOI table, which contains 1,368 new objects. All have dispositions. See the Purpose of KOI activity table for more information, or go to the KOI interactive table.

  • KOI parameters have been re-organized based on size rather than physical properties, which will optimize the data set's usability and the interactive table's performance. The default parameters for this data set have also changed, which may affect data returned in API queries. See the documentation for more information.

  • The archive has also added Markov Chain Monte Carlo (MCMC) posterior chains from the Q1-16 KOI fitting. A compressed tar file (~8 GB) is available for download or via wget script. The document describing the MCMC files is also available.

March 26, 2015: We've added one new planet: BD+20 1790 b, as well as new default parameters for WASP-48 b and updated parameters for HAT-P-23 b, Tau Boo b and 21 HD planets. Also, new data for 64 planet host stars include Teff, log (g) and [Fe/H]. View them in the Confirmed Planets interactive table or Overview pages, or access all parameters in the archive through the extended search tool.

March 12, 2015: We have numerous updates to report this week, both in data and tools:

    Search Extended Planet data tool: This tool allows users to search the extended confirmed planet data sets, which consists of the default values in the Confirmed planet table as well as any additional planet parameters in the archive. There are currently 2,465 planet parameter sets to search.

    Contributed data page: This page documents the data sets contributed to the Exoplanet Archive by the community.

    Updates to Overview pages:

    • A user guide explains how to access and use Overview pages.

    • IRSA Finder charts and 2MASS cutouts included on Overview pages for confirmed planets, KOIs and TCE stars (other stars coming soon): Look for the thumbnails in the upper-right corner of the Overview pages, and click on the image to view as larger version.

    • Reference section on Overview pages: Overview pages now have a section listing all literature references from which data have been obtained.

    Mission star tables available as Mission stars only or Mission stars + ExoCAT: The Mission stars table is now available as either the Mission star lists or those stars plus the 30-pc bounded ExoCAT.

    Standalone tables for all KOI deliveries: These tables deliver faster sorting and other improvements when working with only one KOI activity table at a time. Links to each table are on the Kepler documentation page.

    The Kepler stellar Q1-17 DR 24 table now includes values that enable users to compute completeness (Duty Cycle, Data Span, Robust CDPP, and MES threshold).

    List of interesting objects flag added to Q1-17 TCE table. The TCE table has a flag indicating which objects from the Q1-17 DR 24 pipeline run have been designated by Kepler to be on the "list of interesting objects." See the Kepler Science blog for more information.

March 5, 2015: OGLE 2011-BLG-265L b and WASP-20 b have been added to the Confirmed Planets table, which also has updated default parameters for WASP-28 b and stellar/planet parameters for CoRoT-7 b. We are also hosting microlensing light curve files for MOA 2011-BLG-293L b and MOA 2008-BLG-379L b, which are accessible from the Confirmed Planet Overview pages (see download instructions).

February 26, 2015: Three new K2 planets! K2-3 b, c and d have been added to the Confirmed Planets table. In other K2 news, target lists for K2 campaigns 3 and 4 have been released with the corresponding WISE photometry.
