Exoplanet Orbit Database
Listed in NASA Data Portal
The Exoplanet Orbit Database is a database of well-determined orbital parameters of exoplanets, and their host stars' properties.
Description
This database comprises spectroscopic orbital elements measured for planets orbiting their host stars from radial velocity and transit measurements as reported in the literature. The authors have also compiled fundamental transit parameters, stellar parameters, and the method used for the planets discovery.
This Exoplanet Orbit Database includes all planets with robust, well measured orbital parameters reported in peer-reviewed articles. In addition to this HEASARC representation, the database is available in a searchable, filterable, and sortable form online through the Exoplanets Data Explorer table at <a href="exoplanets.org">http://exoplanets.org</a>, and the data can be plotted and explored through the Exoplanet Data Explorer plotter which is available at that web site.

In their paper, the authors use the Data Explorer to generate publication-ready plots, giving three examples of the signatures of exoplanet migration and dynamical evolution: They illustrate the character of the apparent correlation between mass and period in exoplanet orbits, the different selection biases between radial velocity and transit surveys, and that the multi-planet systems show a distinct semi-major-axis distribution from apparently singleton systems.
This table was first created by the HEASARC in August 2012 based on a machine-readable version of the Exoplanet Orbit Database which was obtained from the authors' web site (<a href="exoplanets.org">http://exoplanets.org</a>), file exoplanets.csv. It is updated usually within a day of whenever the source file is updated. This is a service provided by NASA HEASARC .
