DACE

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 facility based at the University of Geneva (CH) dedicated to extrasolar planets data visualisation, exchange and analysis. DACE is a platform of the Swiss National Centre of Competence in Research (NCCR) PlanetS, federating the Swiss expertise in Exoplanet research. Visualisation and data exchange tools are being developed within the platform to facilitate the comparison of theoretical and observational data. Sophisticated data analysis tools are also developed by several project of  PlanetS  participating to DACE.

At the moment, DACE provides access to ELODIE, CORALIE, HARPS-S and HARPS-N data as well as Keplerian adjustment tools to registered users. Kepler data are available to any visitor of DACE through visualising tools as well as a few basic data analysis tools.

 

Radial velocity measurement of a star hosting a system composed of two giant planets (top figure). The Keplerian model adjusted to the data is represented as a black curve, while the periodogram of the residuals is displayed on the middle figure. The bottom figure represents the amplitude of the signal in m/s within the residuals.

3-Body integration of the planetary system over a time span of 2000 days. Small amplitude oscillations of the orbital is clearly seen in the simulation. N-body simulations are made using Genga developed at the University of Zurich.
