NASA恆星及系外行星數據庫

NASA恆星及系外行星數據庫（、NStED）是NASA用於整理和交叉關聯天文學數據的在線恆星行星目錄數據庫。收集並提供公共數據集。數據包括恆星參數（如位置、大小、溫度）、系外行星參數（如質量、軌道參數）和表徵數據（如徑向速度曲線、光變曲線、圖像、光譜）。

自2011年12月起不再運行，大多數數據和服務已轉移到。

The NStED collects and serves public data to support the search for and characterization of extra-solar planets (exoplanets) and their host stars. The data include published light curves, images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets. All data are validated by the NStED science staff and traced to their sources. NStED is the U.S. data portal for the CoRoT mission.

Search characteristics
Data are searchable either for an individual star or by stellar and planetary properties.

NStED offers direct access to frequently accessed tables:
List of all known planets
List of all known planet-hosting stars

Survey programs
NStED also serves photometric time-series data from surveys that aim to discover transiting exoplanets such as  and the CoRoT.
NStED provides access to over 500,000 light curves from space and ground-based exoplanet transit survey programs, including:

 克卜勒太空望遠鏡
 CoRoT
 匈牙利自動望遠鏡網絡計劃
 跨大西洋系外行星搜尋計劃


The transit survey data are linked to an online periodogram service that can be used to search for periods in the transit survey data sets.  A user can also upload their own time series data to search for periods in their own data.

The planetary orbital parameters are linked to an online  transit ephemeris prediction tool which can be used to predict the probability that an exoplanet may transit and the date/time and observability of the transits.
