ONCE PLATO2.0 WAS CHOSEN BY THE M3 MISSION, THE IAA WAS CHOSEN TO DESIGN, BUILD, VERIFY AND DELIVER THE MAIN INSTRUMENT ELECTRONICS (DIGITAL IN-FLIGHT PROCESSING) UNITS. IN 2014, THE IAA TEAM STARTED PHASE B1 ACTIVITIES. PLATO2.0 WILL ENTER THE IMPLEMENTATION PHASE (B2) IN 2016, FOLLOWING THE SYSTEM REQUIREMENTS REVIEW (SRR) FOR THE SYSTEM. THE NOMINAL LAUNCH OF THE MISSION IS PLANNED AROUND 2024. THIS THREE-YEAR PROPOSAL AIMS TO COVER OUR TECHNICAL CONTRIBUTION AND SCIENTIFIC TO THE MISSION FOR PHASES B2 AND C, THE LATTER FORMALLY ENDING AT THE END OF 2018. DURING THIS PERIOD, THE PRELIMINARY DESIGN AND CRITICAL DESIGN PHASES WILL BE COMPLETED WITH REVISIONS (PDR AND COR), HAVING TO BE DELIVERED TO THE CONSORTIUM AND THIS VARIOUS MEU MODELS. In addition, it also includes technical support for the operation and functioning of the NOMAD INSTRUMENT (EXOMARS) WHEN RESPONSIBILITY IS ASSESSMENT OF THE TECHNICAL EQUIPMENT OF THE IAA._x000D_ _x000D_ The SCIENTIFIC CONTRIBUCTION is combined with two main activities: PARTICIPATION IN THE ADDITIONAL SCIENCE WORK PACKAGE OF PLATO2.0AND THE DEVELOPMENT OF A RELATED SCIENTIFIC PROJECT. THE MAIN OBJECTIVE OF THE SCIENTIFIC PROJECT IS TO STUDY THE STAR WITH PLANETS AS A SINGLE PHYSICAL SYSTEM. THIS NEW APPROACH REQUIRES NEW DEVELOPMENTS IN THE STUDY OF STELLAR INTERIORS, PLANETARY DYNAMICS AND HARMONIC ANALYSIS. THE IAA SCIENTIFIC TEAM HAS EXPERIENCE IN HARMONIOUS ANALYSIS, AND THE UGR TEAM (UNIVERSITY OF GRANADA, ALSO SUBPROJECT OF THIS COORDINATED PROPOSAL) HAS EXPERIENCE IN ASTROSISMOLOGICAL MODELING AND DYNAMICS. THIS IS WHY THE PROJECT IS PRESENTED AS A JOINT IAA/UGR SCIENTIFIC PROPOSAL.
