NASA Exoplanet Archive

<h2 id="exoplanet-data-content">Exoplanet Data Content</h2>
<p>The Exoplanet Archive contains objects discovered through all <a href="/facts/Methods_of_detecting_extrasolar_planets/vFIblQe9">methods</a> (<a href="/facts/Radial_velocity_method/0uTvj3pq">radial velocity</a>, <a href="/facts/Transit_method/vFIblQe9">transits</a>, <a href="/facts/Microlensing/JL0fXQRC">microlensing</a>, <a href="/facts/Methods_of_detecting_extrasolar_planets/vFIblQe9">imaging</a>, <a href="/facts/Astrometry/9ycEEAvD">astrometry</a>, <a href="/facts/Eclipse-timing_method/vFIblQe9">eclipse timing variations</a>, and <a href="/facts/Eclipse-timing_method/vFIblQe9">transit timing variations/TTV</a>) that have publicly available planetary parameters, with a mass (or minimum mass) equal to or less than 30 Jupiter masses.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>

<h2 id="exoplanet-archive-tools-and-services">Exoplanet Archive Tools and Services</h2>

<p>In addition to providing access to large public data sets, the Exoplanet Archive has developed several tools to work with exoplanet and stellar host data.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>
</p>
<ul><li>Interactive Visualizers for Planet Parameters:  These interactive tables display data for confirmed planets, Kepler Objects of Interest (KOIs), Threshold-Crossing Events (TCEs) and target stellar data that users can filter, sort and download or export to other Exoplanet Archive services, such as light curve visualization for the Kepler stars.</li>
<li>Kepler Light Curve Viewer: Interactive display of user-selected quarters for a single Kepler target. Any column from the light curve file can be plotted with or without normalization and sent to the periodogram or phase tool.</li>
<li>Periodogram Service: This tool calculates the periodogram of time series data from the archive or a file uploaded by the user. The service supports three algorithms: <a href="/facts/Lomb-Scargle_periodogram/GYXrRKsB">Lomb-Scargle periodogram</a>, Box-fitting Least Squares (BLS) and Plavchan. Phased light curves for the most significant periods are also available.</li>
<li>Transit and Ephemeris Calculations: This service returns an ephemeris of the times of transit of the exoplanet across its host star. Optionally, for a given longitude and latitude or observatory, the service tabulates times of transit at that location and can calculate the time for secondary transits or other phase points in the orbit.</li>
<li>Application Program Interface (API): This service allows a user access to the contents of the exoplanet and host star table and the Kepler candidate table via a URL or command-line-based query.</li>
<li>Pre-generated Plots: Ready-made plots that provide the community with fast access to presentation material that describe the current state of the exoplanets field in terms of their number and our understanding of their orbital and physical characteristics.</li>
<li>EXOFAST Transit and Radial Velocity Fitting Tool: An important fitting tool for astronomers who want to use transit light curves or radial velocity data and various inputs to create models of planet systems. This web service is based on the original code by Jason Eastman.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a></li></ul>
<h2 id="transit-survey-data-in-the-exoplanet-archive">Transit Survey Data in the Exoplanet Archive</h2>
<p>The Exoplanet Archive serves photometric time-series data from surveys that aim to discover transiting exoplanets, such as the Kepler Mission and CoRoT. The database provides access to over 22 million light curves from space and ground-based exoplanet transit survey programs, including:

<li><a href="/facts/United_Kingdom_Infrared_Telescope/HmyCfEPV">UKIRT</a> Microlensing Survey data</li></ul>
<p>The Exoplanet Archive offers search and filtering capabilities for exoplanet stellar and planetary properties, Kepler planetary candidates, and time series data sets. All data in the Exoplanet Archive are vetted by a team of astronomers and the original literature references are available.
</p><p>The Exoplanet Archive supports interactive visualization of images, spectra, and time series data and maintains its own stellar cross-identification to minimize ambiguity in multiple star components.
