Infrared Processing and Analysis Center in the context of IRAS

J. Davy Kirkpatrick is an American astronomer at the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena, California. Kirkpatrick's research was named one of the top ten science accomplishments of the first ten years (1992–2002) of the W. M. Keck Observatory and one of the Top 100 Stories of 2011 by Discover Magazine.

The NASA Exoplanet Archive is an online astronomical exoplanet catalog and data service that collects and serves public data that support the search for and characterization of extra-solar planets (exoplanets) and their host stars. It is part of the Infrared Processing and Analysis Center and is on the campus of the California Institute of Technology (Caltech) in Pasadena, CA. The archive is funded by NASA and was launched in early December 2011 by the NASA Exoplanet Science Institute as part of NASA's Exoplanet Exploration Program. In June 2019, the archive's collection of confirmed exoplanets surpassed 4,000. (Compare: As of 18 December 2025, there are 6,065 confirmed exoplanets in 4,518 planetary systems, with 1,025 systems having more than one planet.)

The archive's data include published light curves, images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets. The archive also develops Web-based tools and services to work with the data, particularly the display and analysis of transit data sets from the Kepler mission and COnvection ROtation and planetary Transits (CoRoT) mission, for which the Exoplanet Archive is the U.S. data portal. Other astronomical surveys and telescopes that have contributed data sets to the archive include SuperWASP, HATNet Project, XO, Trans-Atlantic Exoplanet Survey and KELT.
