and 2011-12 archives.
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,
HIP 109600 b,
HD 35759 b,
HIP 109384 b,
HD 220842 b,
HD 12484 b,
HIP 65407 b & c and K2-28 b. See the Planet Overview pages or go to the Confirmed Planets table.
- 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:
- We've updated the KOI Radius vs. Period movie that illustrates the progress of Kepler discoveries over time. This update includes Q1-17 DR 24 data. Watch it on our Videos page.
February 4, 2016: Our latest updates include:
- This week we welcome radial velocity planets HD 5583 b and BD+15 2375 to the Archive and various updated stellar and planetary parameters. See their Overview pages or go to the Confirmed Planets table.
- 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.
January 28, 2016: New this week:

&where=k2_campaign=8" in your query.
For your convenience, here is the pre-built HTTP query for all K2 Campaign 8 targets:
- Our Frequently Asked Questions (FAQ) page is updated regularly to address common user questions, such as "How do I find all the transiting confirmed planets?" and "How are Kepler numbers assigned?" Take a look, and if you don't see an answer to a question you'd like to ask, submit a Helpdesk ticket.

- We've also updated values for the Host Star Relative Probability Source Flag (
pp_host_prob_prov) for 315 false positive KOIs; view them in the Kepler Astrophysical Positional Probabilities table.
January 14, 2016: This week's updates:
- HD 33844 b and c have been added, as well as various updated planetary parameters and eight new transit spectroscopy data files.
We've updated two movies of our pre-generated plots that can be viewed from our Videos page:
- 26 Years of Discoveries, which shows the number of exoplanet discoveries in mass-period space from 1989 through 2015, and
- Exoplanets: Detection by Discovery Year, a histogram showing the total number of exoplanet discoveries by detection method through 2015.
We are in the process of updating the third movie, KOI Radius vs. Period.
January 5, 2016: Happy new year! Here are some updates for you:
- New K2 Candidates Table:
We've created a new K2 Candidates interactive table with information about K2 planetary candidates. The collected data are currently from two refereed publications: Montet et al. 2015 and
Vanderburg et al. 2015. All presented data are linked to the corresponding publication. Access the table from the Data pull-down menu on any Archive web page and click the K2 Candidates link.
