Promoting the access to and use of seismic data in a large scientific community: The data handling and archiving Work Package of the SPACEInn Programme.
Eric Michel (Observatoire de Paris-LESIA), WP3 participants (SPACEInn project)
The growing amount of seismic data available from space missions (SOHO, CoRoT, Kepler, SDO,…) but also from ground-based observations (GONG, Bison, ground-based large programmes…), stellar modelling and numerical simulations, creates new scientific perspectives e.g. to characterize stellar populations in our Galaxy or to characterize planetary systems by giving model-independent global properties of stars such as mass, radius, and surface gravity within several percent accuracy, as well as to constrain the age. These applications address a broad scientific community beyond the solar and stellar one and require combining indices elaborated with data from different data bases (e.g. Space seismic archives and ground-based spectroscopic surveys). It is thus a basic requirement to develop a simple and efficient access to these various data resources and dedicated tools. In the framework of the European project SPACEInn (FP7), several data sources have been developed or upgraded. The Seismic Plus Portal has been developed, where synthetic descriptions of the most relevant existing data sources can be found, as well as some tools allowing to locate existing data for given objects or period and helping the data query. This project has been developed in the Virtual Observatory (VO) framework. In this talk, we will give a review of the various facilities and tools developed within this programme. The SpaceInn project (“Exploitation of Space Data for Innovative Helio- and Asteroseismology” ) has been initiated by the European Helio- and Asteroseismology Network (HELAS).
