The NASA/IPAC/NExScI Star and Exoplanet Database

TL;DR

The NStED database provides comprehensive stellar and exoplanet data supporting NASA's mission goals, including a large star catalog and an archive for high-precision photometric surveys of transiting exoplanets.

Contribution

Findings

Serves data for 140,000 stars with detailed parameters

Archives photometric survey data from multiple projects

Facilitates mission planning and exoplanet research

Abstract

The NASA/IPAC/NExScI Star and Exoplanet Database (NStED) is a general purpose stellar archive which supports NASA planet-finding and planet-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 (NStED-ETSS). We present summaries of these components. The NStED stellar database currently serves published parameters for 140,000 stars. These parameters include coordinates, multiplicity, proper motion, parallax, spectral type, multiband photometry, radial velocity, metallicity, chromospheric and coronal activity index, rotation velocity/period, infrared excess. NStED-ETSS currently serves data from the TrES survey of the Kepler field as well as dedicated photometric surveys of four stellar clusters. 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.
