The NASA Star and Exoplanet Database: The ExoPlanet Transit Survey Service
Abstract
The NASA Star and Exoplanet Database (NStED) is a general purpose stellar archive with the aim of providing support for NASA's planet finding and characterization goals, stellar astrophysics, and the planning of NASA and other space missions. There are two principal components of NStED: a database of 140,000 nearby stars and exoplanet-hosting stars, and an archive dedicated to high precision photometric surveys for transiting exoplanets. We present a summary of the NStED Exoplanet Transit Survey Service (NStED-ETSS) content, functionality, tools, and user interface. NStED-ETSS currently serves 150,000 stars from the TrES Survey of the Kepler Field as well as dedicated photometric surveys of four stellar clusters, with an anticipated expansion of another 150,000 within the next year. NStED-ETSS aims to serve both the surveys and the broader astronomical community by archiving these data and making them available in a homogeneous format. Examples of usability of ETSS include investigation of any time-variable phenomena in data sets not studied by the original survey team, application of different techniques or algorithms for planet transit detections, combination of data from different surveys for given objects, statistical studies, etc. We illustrate the use of ETSS and show examples of the data contained in the database.
