Archive 2.0 Release Notes

On April 29, 2021, the Planetary Systems tables became the archive's default data tables for published planetary system data, and the retiring tables were phased out.

To enhance the user experience, the NASA Exoplanet Archive developed new tables of planetary systems data that consolidated the functions of three existing tables that have been retired. The new Planetary Systems tables were rolled out over a 1.5-year period in various phases, giving users plenty of time to test and provide feedback, and also to allow a gentle transition from the retiring tables to the new tables.

In addition, the archive introduced a new Table Access Protocol (TAP) service to eventually replace the archive's application programming interface (API), and the multiple overview pages for confirmed planets, planetary candidates, and other objects have been consolidated into redesigned System Overview pages.

This page lists some of features that have been added with each release. Please see the Transition page for information on how to transition your work from the retired tables to the new Planetary Systems tables.

We invite and encourage feedback from our users about all of our data and services. You can submit questions, requests, and report issues through the Helpdesk, or contact us through Facebook or Twitter.

Planetary Systems (PS) Table Release Notes

Release VersionRelease Date Changes
1.0 April 2021
(current)
No functional or user interface changes. Status updated to being the archive's default table for self-consistent planetary system data.
Gamma December 2020
  • Update to data content, including more complete information on the number of stars in a system.
  • TICv8 asymmetric uncertainties handled properly.
  • Null references are properly attributed.
  • Stellar spectra columns updated to reflect proper published planet-star solutions.
  • Overall general improvements on the content based upon continued data validation.
  • Numerous bug fixes to graphical interface, including:
    • Correct filtering and sorting on date and character columns.
    • Updates to the columns shown by default.
  • Update to TAP service to include the Gaia ID (already included in the interactive display).
Beta August 2020
  • Various bug fixes
  • Expanded and updated data content, including Gaia IDs, improved stellar multiplicity reporting, and improved detection flag reporting
Alpha December 2019 Initial release:
  • Combined data from Confirmed Planets and Extended Planet Data tables.
  • Each row contains planet, stellar and system (TESS Input Catalog) properties.
  • All solutions for confirmed exoplanet systems are now available in a single table, including Kepler, K2, and TESS candidate solutions.
  • The new table also provides a nearly complete identification of published stellar companions in confirmed planetary systems.
  • We've added measurements of projected and true planet obliquities.
  • The table contains a summary of data sets available in the archive for a given system.

Gamma March 2021
  • Update to include stellar parameters that were not published as part of the planetary solutions, providing a more complete view of the properties of the host stars.
Beta December 2020
  • Update to data content, including more complete information on the number of stars in a system
  • TICv8 asymmetric uncertainties handled properly.
  • Null references are properly attributed.
  • Stellar spectra columns updated to reflect proper published planet-star solutions.
  • Planetary Systems Composite Parameters population has improved population of parameters.
  • Overall general improvements on the content based upon continued data validation.
  • Numerous bug fixes to graphical interface, including:
    • Correct filtering and sorting on date and character columns.
    • Updates to the columns shown by default.
  • Update to TAP service to include the Gaia ID (already included in the interactive display).
Alpha August 2020 Initial release; see About the Planetary Systems Composite Planet Data Table for a more complete description

Redesigned System Overview Pages Release Notes

Release VersionRelease Date Changes
1.0 March 2021 (current)
  • Implemented overviews for candidate-only systems (e.g., KOI-753, EPIC 201127519).
  • Services and interfaces that link to overviews default to new overviews, e.g., interactive tables and the Explore the Archive search on the home page.
Beta December 2020
  • Improved visualization of multi-star systems.
  • More complete support for Ancillary Data associated within a system.
  • Updates to the color schemes, highlighting, and labeling.
Alpha December 2019Initial release:
  • Summarized system architecture, data and graphics at the top of the page for quick reference, including flags for planets that are refuted or considered controversial. (See example)
  • A special Exoplanet Archive Notes section for additional information about the system, such as whether one of its planets had been refuted and then reinstated.
  • Color-coded solutions show all planet parameters associated with a given set of stellar parameters. (See example)
  • Collapsible and expandable sections allow users to customize their view of the available data.
  • Flexible design supports various types of system architectures.
  • A Bibliography section lists all published literature references included in the archive, with links to the papers in ADS. (See example)
