The NASA Star and Exoplanet Database: The Stellar Archive
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 (mostly Hipparcos) stars and exoplanet-hosting stars, and an archive dedicated to high precision photometric surveys for transiting exoplanets.
We present a summary of the NStED stellar database, functionality, tools, and user interface. NStED currently serves the following kinds of data (where available): coordinates, multiplicity, proper motion, parallax, spectral type, multiband photometry, radial velocity, metallicity, chromospheric and coronal activity index, rotational velocity/period, infrared excess, etc. Furthermore, the following derived quantities are given wherever possible: distance, effective temperature, mass, radius, luminosity, age, space motion, and physical/angular dimensions of habitable zone. Queries to NStED can be made using constraints on any combination of the above parameters. In addition, NStED provides tools to derive specific inferred quantities for the stars in the database, cross-referenced with available extra-solar planetary data for those host stars.- Publication:
