Analysis of information sources in references of the Wikipedia article "NASA Star and Exoplanet Database" in English language version.
The NASA Stellar and Exoplanet Database (NStED) was a stellar archive created to support NASA's goals of finding and characterizing exoplanets (Stauffer et al. 2008). NStED was discontinued in 2011 and replaced with the NASA Exoplanet Archive, which launched on December 5, 2011. All of NStED's exoplanet data were retained and moved to the NASA Exoplanet Archive, as well the stellar parameters for exoplanet host stars and some hosted data sets.
