Important Update Regarding NStED

The NASA Exoplanet and Stellar Database (NStED) is transitioning to a new service called the NASA Exoplanet Archive. The new service is funded by NASA through the NASA Exoplanet Science Institute (NExScI) to serve the user community working with exoplanet data, primarily transit data sets from Kepler and CoRoT, by providing long-term data curation and analysis tools. Data content will include exoplanet and stellar host properties and Kepler candidate properties. Stellar parameters for stars without known planets will no longer be available. Additional content will include contributed exoplanet data from space- and ground-based projects.

The transition will take place in early December.
Please submit any questions or comments to the Helpdesk.


What is NStED?

The NASA Star and Exoplanet Database (NStED) collects and serves public data to support the search for and characterization of extra-solar planets (exoplanets) and their host stars. The data include published light curves, images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets. All data are validated by the NStED science staff and traced to their sources. NStED is the U.S. data portal for the CoRoT mission.

Latest News


October 31, 2011: The Periodogram Service has been updated with enhanced features, including a new Light Curve Viewer that allows users to submit time-series data and view the light curve before sending the data to the Periodogram Service for further processing. The viewer is accessed from the Periodogram Service upload page. Other enhancements include:

  • The Most Significant Periods for submitted data may be downloaded as a text file from the results page.
  • Users may now specify up to three time or data constraints for each periodogram job.
  • Periodogram results may be viewed either in linear or log format.
  • Additional information has been added to the Algorithms documentation.
  • A small list of known issues has been added to the Periodogram Service and Light Curve Viewer help documentation.

October 6, 2011: Light curves from Kepler Q3 are now available, and all Kepler light curves are in the updated FITS format. Use the Kepler Public Data search interface to access the light curves.

October 26, 2011: NStED has added 100 planets to the database.

NStED Service Includes 1,235 Kepler Exoplanet Candidates

The 1,235 Kepler exoplanet candidates have been integrated in the Kepler light curve service at NStED. Users can search on stellar, planet candidate, and transit candidate properties, retrieve a list of candidates matching the search criteria, and use the list to retrieve all public light curves associated with those candidates.

The planet candidate interface, which is integrated with the NStED Periodogram Service, can be accessed from NStED home by clicking the Kepler Planetary Candidates link in the Transit Survey Light Curves section.
