Contribution

This paper introduces a centralized, accessible platform with diverse data and tools specifically designed for exoplanet research, enhancing data accessibility and analysis capabilities.

Findings

Includes data on all published exoplanets and Kepler candidates

Provides tools for light curve analysis and transit prediction

Supports various data types like spectra and radial velocities

Abstract

We describe the contents and functionality of the NASA Exoplanet Archive, a database and tool set funded by NASA to support astronomers in the exoplanet community. The current content of the database includes interactive tables containing properties of all published exoplanets, Kepler planet candidates, threshold-crossing events, data validation reports and target stellar parameters, light curves from the Kepler and CoRoT missions and from several ground-based surveys, and spectra and radial velocity measurements from the literature. Tools provided to work with these data include a transit ephemeris predictor, both for single planets and for observing locations, light curve viewing and normalization utilities, and a periodogram and phased light curve service. The archive can be accessed at http://exoplanetarchive.ipac.caltech.edu.
