New Features of the Exoplanet Orbit Database at Exoplanets.org

We report a series of updates and enhancements on the Exoplanet Orbit Database (EOD), which contains peer-reviewed orbital and transit parameters of exoplanets and stellar parameters of their host stars. Along with inputting new planets, we regularly check the Astrophysics Data System and arXiv.org for updates to the orbits of known planets. Since December 2010, the EOD expanded from 427 planets to 640 planets, as of September 2012. The EOD can be explored through the Exoplanet Data Explorer Plotter and Table, available at http://exoplanets.org. Additions to the reported fields include stellar radius, asymmetric uncertainties, references for almost all parameters, and more. We are preparing to merge the EOD with data from the Exoplanet Archive's Kepler candidate list, and so have added many Kepler fields to the EOD including Kepler magnitude. This will allow for the confirmed exoplanets to be merged with Kepler candidates in the Exoplanet Data Explorers (EDE). We also plan to add microlensing and imaged planets, so that the entire population of high-quality, peer-reviewed planet detections can be displayed in the Table and Plotter EDEs. To minimize data entry errors in stellar parameters, a new program we wrote automatically retrieves fields like magnitudes, right ascension and declination, and the SAO identifier from SIMBAD data. We have also cross-examined our data with a few other independent databases to screen for typos and errors. We are also show fits of orbits of new and known planets of almost two dozen stars. Using the latest Keck velocities, we update solutions for several long period planets.
