The NStED Exoplanet Transit Survey Service

TL;DR

The NStED Exoplanet Transit Survey Service (ETSS) archives and provides access to high-precision photometric data from various exoplanet surveys, supporting diverse astronomical research and planet detection efforts.

Contribution

This paper introduces the NStED-ETSS platform, a homogeneous archive for transit survey data, enhancing data accessibility and usability for the astronomical community.

Findings

Serves data from TrES and stellar cluster surveys

Enables investigation of time-variable phenomena

Supports combined analysis of multiple surveys

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 (currently) 140,000 nearby stars and exoplanet-hosting stars, and an archive dedicated to high-precision photometric surveys for transiting exoplanets. We present a summary of the latter component: the NStED Exoplanet Transit Survey Service (NStED-ETSS), along with its content, functionality, tools, and user interface. NStED-ETSS currently serves data from the TrES Survey of the Kepler Field as well as dedicated photometric surveys of four stellar clusters. <CA>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. Examples of usability of ETSS include investigation of any time-variable phenomena in data sets not studied by the original survey team, application of different techniques or algorithms for planet transit detections, combination of data from different surveys for given objects, statistical studies, etc. NStED-ETSS can be accessed at \tt{http://nsted.ipac.caltech.edu}
