The NASA Exoplanet Science Institute (NExScI) is pleased to announce a
significant update to the NASA Star and Exoplanet Database (NStED). Each
of the 210,000+ public Kepler light curves are integrated with the
newly-released NStED periodogram service. The periodogram service
employs three different algorithms and generates a periodicity rank for each tested frequency
and a phased light curve for each peak in the periodogram. The
periodogram parameters are adjustable through a web-based interface
allowing users to refine the periodicity search. The Kepler data are
searchable at NStED from

NStED provides a portal to data from the Hungarian-made
Automated Telescope Network (HATNet) project. The initial release
includes more than 5000 lightcurves of variable stars detected by the
HATNet project from 72 HATNet fields with declinations between +15
degrees and +52 degrees. The survey covers approximately 4000 square
degrees, or roughly 10\% of the sky. The HATNet data are available at
