November 19, 2015: This week, we added 10 new planets and removed 4 that have published refutations. There are also several updated parameters and four new transit spectroscopy data files. The 10 new planets, the data for which can be viewed in the Confirmed Planets table or in individual Overview pages, are: HD 219134 f, g & h, HAT-P-50 b, HAT-P-51 b, HAT-P-52 b, HAT-P-53 b, HD 1461 c, HD 204313 c and HD 175607 b.

November 12, 2015: We have the data for the rocky and nearby Earth-sized planet called GJ 1132 b that was announced in Nature this week. See the planet's Overview page or the published paper. (Image credit: Dana Berry/SkyWorks/NASA)

November 5, 2015: Our Confirmed Planets table now contains data for HAT-P-57 b, bringing our total planet count to 1,904.

October 29, 2015: We've populated the Transit Spectroscopy table with published transmission spectra for over 50 exoplanets! Now you can investigate and plot spectroscopy values from the UV to the MIR. Contact us to contribute your own published data. We also welcome values for published transmission spectrum figures.

Also, our Planet Occurrence Rate page contains a compilation of published, refereed papers that derive planet occurrence rates. Take a look and let us know if we missed one!

October 22, 2015: This week we welcome newly confirmed planets OGLE 2013-BLG-0723L B b and HD 155233 b, as well as new transit spectroscopy data and updated planet and stellar parameters. Go the Confirmed Planets interactive table for planet data, or click the Transit Spectroscopy button on the home page.

Also, our K2 Targets table now includes objects selected for observation during campaigns 6 and 7. The table can also be accessed through the application programming interface (API).

NASA's Eyes on Exoplanets application (shown here running on COBRA kiosks at the National Air and Space Museum in Washington, D.C.) contains a fully rendered 3D universe that gives users a closer look at exoplanets. The experience is even more realistic because it's loaded with data from the Exoplanet Archive. (Image credit: Rachel Akeson, NASA Exoplanet Science Institute)

October 15, 2015: Here is a summary of our data updates this week:

  1. NINE newly confirmed planets, various updated parameters, and new transit spectroscopy have been added to the Archive. The new planets are: K2-22 b, WASP-41 c, WASP-47 c, WASP-47 d & e, HD 11755 b, HD 12648 b, HD 24064 b, and 8 UMi b.

  2. We've added a new presentation-ready radius vs. period scatter plot for all Confirmed Planets and Kepler Candidates. It's the first plot listed in the Kepler Candidates (right) column on our Pre-Generated Plots page.

October 1, 2015: We've made several improvements to the Archive this week:

  1. JWST Transit Predictions Now Available! We've updated the Transit and Ephemeris Service to include transit predictions for the James Webb Space Telescope (JWST), which can be used for planning purposes when writing proposals for telescope time. Note that the tool also supports Spitzer for this purpose.

  2. Updated Default Columns: The Confirmed Planets table has been updated and some default columns have changed. If you use our API service with the default setting, this change may affect your pre-programmed queries. The updated parameters are:

    New defaults: Best Planet Mass measurement in Jupiter masses (pl_bmassj), Provenance of Best Planet Mass (pl_bmassprov=Mass, Msin(i)/sin(i), or Msini), Optical Magnitude (st_optmag), Optical Magnitude Band (st_optband=V (Johnson) or Kepler-band), and Date of Last Update (rowupdate)

    No longer defaults: Hipparcos Name (hip_name), HD Name (hd_name), Planet Mass in Jupiter masses (pl_massj), Planet Msini in Jupiter masses (pl_msinij), and V-band (Johnson) Magnitude (st_vj)

    A complete description of each parameter is available on the Exoplanet Table Contents page. For API service troubleshooting, see the API User Guide. (Note: Use the "select=* keyword to retrieve all available parameters from the exoplanets data table, or by retrieving specific parameters with "select=pl_def_name," for example.)

    To learn more about default parameters in the Archive, see What are default parameters? in the FAQ.

  3. New Predicted Observables for Exoplanets (POE) calculation: The Predicted Observables for Exoplanets (POE) tool now calculates the maximum projected sky separation between putative star-planet pairs, for use in planning direct-imaging observations. A detailed description is provided in the How the Predicted Observables for Exoplanets are Calculated document.

  4. More Direct Access to Overview Pages: The default behavior of the Explore the Archive box on the home page now takes you directly to an overview page when a name is provided. A radius is only required when searching around the source or with coordinates. See the Overview User Guide for more information.

  5. New Search Interface for K2 Targets: Our available K2 targets (through Campaign 5) are now accessible through a search interface, much like the ones for our SuperWASP and Kepler Stellar data sets.

September 24, 2015: The Kepler project has closed the Q1-Q17 DR24 KOI table. No further changes will be made to that data set. See the Purpose of KOI activity table for details.

September 18, 2015: This week we have two new K2 confirmed planets: K2-21 b and K2-21 c, as well as updated parameters and new Transit Spectroscopy data.

Also, the latest Q1-Q17 DR24 KOI delivery contains updated comments to report the minor flags set by the Robovetter, and values for single- and multiple-event statistics, quarters, and the number of transits for all KOIs. See the Purpose of KOI activity table for details.

September 10, 2015: One confirmed planet added this week: HD 164595 b, as well as updated parameters, and addition, more Transit Spectroscopy data. Access stellar and planet parameter data at the Confirmed Planets interactive table.

September 3, 2015: This week's updates:

August 27, 2015: This week's updates:

August 19, 2015: Our confirmed planet data now includes two new literature reference parameters: Default Reference (pl_def_name) and Discovery Reference (pl_disc_refname), as well as discovery telescope and instrument information (pl_locale, pl_facility, pl_telescope, & pl_instrument). There are two ways to access them:

  1. In the Confirmed Planets interactive table using the Column Controls tool to add the parameters to the table.

  2. Through the API using the "select=* keyword to retrieve all available parameters from the exoplanets data table, or by retrieving specific parameters with "select=pl_def_name" (for example).

More information about the new API parameters is available in the column definitions documentation.

August 14, 2015: The newly announced young Jupiter with the lowest mass to be directly imaged, 51 Eri b, was added to the Archive today, as well as new planets HATS-13 b, HATS-14 b and OGLE 2012-BLG-0563L b. Click the links for their Overview pages, read the press release, or see them all in the Confirmed Planets interactive table.

August 6, 2015: Among the 4 planets added this week is HD 219134 b, which was announced last week as the nearest rocky planet outside our Solar system. The three other planets are part of the same system: HD 219134 c, d & e. See the NASA press release and the Confirmed Planets interactive table.

We've also added a new movie to our Videos page: a histogram of exoplanet discovery by detection method through 2014. (We'll update the movie to include 2015 discoveries at the end of the year.) You are welcome to download and use the movie as needed. Note: Our movies are also accessible from the Pre-Generated Plots page.

July 30, 2015: We've added several new Kepler data products this week, including two Occurrence Rate products (first two bullets):

  • Kepler False Positive Table: The Kepler False Positive Working Group (FPWG) conducted a detailed examination of declared false positives in the Kepler Object of Interest (KOI) tables, which has resulted in a new table of certified false positive KOIs. View the FPWG interactive table and read the documentation for more information.

  • Kepler Astrophysical Positional Probabilities: The new KOI APP interactive table examines the possibility of the transit signal arising from an astrophysical source other than the target star. For each KOI, this table lists up to two stars with the highest probabilities of being co-located with the source of the observed transit, as well as the probability of the transit being on an unknown background source. For more information, read the documentation.

  • TCE Autovetter Columns: The autovetter is a machine-learning classifier that dispositions TCEs into the three classes, thus producing a table of planet candidates. New parameters have been added for TCE Autovetter data in the TCE Q1-Q17 DR 24 interactive table and API. For more information, read the Q1-17 DR 24 documentation.

Also, for your K2 data browsing pleasure, we've created a K2 Names interactive table and enabled our API to return its parameters, which you can read all about in the documentation.

Finally, microlensing light curves for stars known to host planets are now available for batch download on our Bulk Download page.

July 23, 2015: Today's updates:

  • Added: Kepler-452 b and HAT-P-56 b! Kepler-452 b, the system most similar yet to our own Earth-Sun system that NASA announced today, is in the Archive. Access the Overview page and read the discovery paper and NASA press release. We've also added HAT-P-56 b; both new planets are in the Confirmed Planets interactive table.

  • Updated 97 KOI Dispositions: The Kepler Mission has provided updated dispositions on 97 Kepler Objects of Interest (KOIs) for Q1-17 DR24. More information is in the Purpose of KOI activity table, or go directly to the KOI interactive table.

  • New Transit Spectroscopy: There are new spectra for GJ 3470 b and WASP-19 b. View them and their literature references in the Transit Spectroscopy interactive table.

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.
