Data and Analysis Center for Exoplanets

Project Leader: S. Udry; co-leader: B. Moore
Project Scientist: D. Ségransan

The Data Analysis Center for Exoplanets (DACE) is a web platform based at the University of Geneva (CH) dedicated to extrasolar planets data visualisation, exchange and analysis.

Published observational data like radial velocities, light curves and imaging measurements are available as well as sophisticated analysis tools. Keplerian models can be analysed using synthetic planetary populations and evolution tracks provided by the university of Bern. Numerical simulations can be done by N-Body algorithms developed by the university of Zurich and running on GPU cards. DACE also contains star position tool helping astronomers to prepare future observations according to the location of the observatory and time constraints.

These tools are developed in collaboration with the PlanetS sub projects and integrated in the platform. The platform offers the possibility to run long computations in background as jobs. In this manner, the projects can contribute by providing analysis code implemented in different programming languages.
