- We've added posterior distributions for stellar properties to the Kepler Stellar Q1-17 DR 25 table, which can be accessed from the Bulk Download page.
May 19, 2016:
- Five new planets this week: HD 191806 b, HD 214823 b, HD 221585 b, MOA 2013-BLG-605L b, and Kepler-1647 b. View their respective Overview pages or go to the Confirmed Planets interactive table. We've also removed 1 planet based on a published refutation.
- We've integrated K2 campaign 7 long cadence light curves into the Archive. To access them:
- Go to the K2 Targets search interface and filter K2 Campaign as = 7, then click Submit Search.
- From the interactive results table, click on the icon. If a light curve is available, you'll see a K2 Time Series and Periodogram link.
- New Extended Planet Data Application Programming Interface (API): As requested by users, the Extended Planet Data (Search) may now be accessed through our API (
multiexopars). For your convenience, here is a pre-built query. To build a new query or refine the one provided above, see the API User Guide and list of available parameters in the Extended Planet Data Contents page.
May 10, 2016: 1,285 New Planets (Not a typo!)
Today marks another milestone in exoplanet science: the Kepler Mission's media announcement revealed the validation of 1,284 Kepler exoplanets by Morton et al. 2016. We've also added Kepler-539 c from another paper (Mancini et al. 2016), bringing our confirmed exoplanet count to 3,264.
Each planet and its parameters have been added to the Archive's Confirmed Planets table; there is also a filtered interactive table containing only the planets added today.
May 5, 2016: New Planets and TCE Data!
- We've added 14 planets this week, including the TRAPPIST system that has been in the news: TRAPPIST-1 b, c & d, K2-19 d, K2-31 b, K2-32 b, K2-32 c, K2-32 d, K2-34b, WASP-119 b, WASP-124 b, WASP-126 b, WASP-129 b, WASP-133 b. We've also removed OGLE 2013-BLG-0723L B b based on a published refutation.
- The TCE list and DV data from the DR 25 Kepler pipeline is now available. The DV light curve FITS files now include the whitened data as used for planet searching by the pipeline. Note that the DR 25 TCEs are not yet
associated with KOIs and so are not accessible from the KOI tables. Access the data from the Kepler TCE documents and Kepler Mission pages (click the Q1-17 DR 25 links), and learn more in the API documentation.
April 28, 2016: A few updates:
- We've added two new planets, KELT-10 b and OGLE-2012-BLG-0724L b, as well as several updated parameters. View the planet's Overview pages or the Confirmed Planets interactive table.
- The Archive has integrated Q1-17 DR 25 Kepler long cadence light curves in our visualization and download tools, which includes the Periodogram and Kepler Time Series Viewer tools. Note that the short cadence light curves are still version DR 24. More information about the DR 25 data is in the release notes.
- Radial velocity curves obtained by the MARVELS team described in Thomas et al. 2016 have been added to our holdings. The full data set is in this .tar file; individual RV files are also available in the Overview Pages for the relevant stars.
April 14, 2016:
- This week we have another K2 planet, K2-30 b, plus new microlensing curves for OGLE-2015-BLG-0966L.
- K2 Campaign 9 targets are available! Find them through the K2 Targets search interface, or by using our API service by specifying
&where=k2_campaign=9 in your query.
For your convenience, here is the pre-built HTTP query for all K2 Campaign 9 targets:
April 7, 2016: In support of the K2 microlensing observations (Campaign 9) that start today, we're pleased to announce the release of the ExoFOP-K2 C9 site. Users may access the list of microlensing events happening in the field of view as well as detailed pages for each event. No login required. More information is in the Kepler press release.
March 31, 2016:
This week we welcome new planet TYC 3667-1280-1 b, which was discovered by radial velocity. Click on the name to view its Confirmed Planet Overview page, or see the Confirmed Planets interactive table.
March 24, 2016: Three new planets added this week. One of the planets, K2-29 b, was also found in our SuperWASP light curves with the help of our Explore The Archive service. This allowed the discovery team to increase the observing baseline by 11 years, thereby dramatically improving the ephemeris.
The other planets are HATS-17 b and MOA 2011-BLG-028L b. Click the links to see their Planet Overview pages or go to the Confirmed Planets table.
March 17, 2016: This week we've added 5 confirmed planets: 2 discovered with transits, 2 by radial velocity, and 1 with microlensing. The planets are HIP 8541 b, HIP 74890 b, OGLE 2015-BLG-0966L b, KELT-14 b, and KELT-15 b. Click the links to see their Planet Overview pages or go to the Confirmed Planets interactive table.
March 10, 2016: This week!
- We've added Kepler-167 d and e to the Archive, plus various updated stellar and planetary parameters. See the Confirmed Planets table for the data.
- We've also removed HD 7449 c and HD 99492 c, based on published refutations. For details, see the Removed Targets page.
- Based on the new results from Johnson et al. 2016, HD 219134 e and h are now considered to be the same object. This means that if you search for HD 219134 e, your results will be for HD 219134 h.
March 3, 2016:
As requested by users, K2 Candidate data may now be accessed through our Application Programming Interface (API). For your convenience, here is a pre-built query. To build a new query or refine the one provided above, see the API User Guide and list of available parameters in the K2 Candidates Data Column Definitions.
February 25, 2016:
This week's updates:
- 14 planets have been added: KELT-4 A b, HD 141399 b, c, d & e, HD 143105 b,

- Additional Stellar Data for Kepler: Distance and extinction (Av) values have been added to the Kepler Stellar table related to the Q1-17 DR 25 release. These parameters are available at the Kepler Stellar search interface and API. The update is also reflected in the documentation.
- Updated K2 Targets Default Columns: Stellar parameters from Huber et al. 2016 have also been added to the K2 Targets search interface and API. As a result, some default columns have changed. If you use our API service with the default setting, this change affects your pre-programmed queries. The updated parameters are:
New defaults: Stellar Effective Temperature (k2_teff), Stellar Mass (k2_mass), Stellar Radius (k2_rad), and Ks-band (2MASS) (k2_kmag).
No longer defaults: Number of K2 Proposal Identifiers (k2_npropid)
A complete description of each parameter is available on the K2 Targets Data Column Definitions page. For API query troubleshooting, see the API User Guide. (Note: Use
To learn more about default parameters in the Archive, see What are default parameters? in the FAQ.
select=* to retrieve all available parameters from the
k2targets data table; otherwise, specify parameters by database column name, e.g.
February 11, 2016: Several updates this week, including:
- New planets Pr0211 c, K2-27 b and K2-24 b & c are part of the Archive today, as well as updated stellar and planetary parameters. See their Overview pages or go to the Confirmed Planets table.
- Kepler Stellar Q1-17 DR 25 data are available through the Archive's Kepler Stellar search interface and application programming interface (API). These data comprise the stellar parameters used for the Q1-17 DR 25 pipeline run.
Other products from this pipeline run will be available in the next few months. Documentation is posted on the Kepler Stellar Documentation page.
For your convenience, here is the pre-built HTTP query for all Kepler Stellar Q1-17 DR 25 data in IPAC ASCII table format:

- Have you tried out the redesigned Periodogram service yet? The old Periodogram service will be operational until the end of February, at which point it will be decommissioned. We highly recommend switching to the new service immediately. For some sample use cases with the new interface, see the recipes for a variable star and star spot evolution.
For more information and help on using the Periodogram service, consult the user guide by clicking on the Documentation tab within the service's interface.
