Summary
PLAnetary Transits and Oscillations of stars (PLATO) is the third medium-class mission in ESA’s Cosmic Vision programme. PLATO was adopted by ESA Science Programme Committee in June 2017 and is due to be launched in 2026. Its objective is to find and study a large number of extrasolar planetary systems, with emphasis on the properties of terrestrial planets in the habitable zone around solar-like stars. PLATO has also been designed to perform seismology of stars, enabling the precise characterisation of the planet host star, including its age.
The WP12 STEllar SCIence work package (STESCI hereinafter) plays a key role in reaching the mission’s science goals : its responsibility is to specify the methods for the determination of accurate and precise stellar parameters for all the dwarf and subgiant stars later than spectral type F5 from the photometric light curves obtained from the instrument. In other words, WP12 will be in charge of providing the specifications for the PLATO Data Center (PDC) to deliver seismic spectra (data products DP3), surface rotation and activity indicators (DP4), radii, masses and ages (DP5) for the hundreds of thousands of low-mass stars of the PLATO core programme. In addition, intermediate data products need to be prepared too before launch, and will continue to be provided during the mission operation.
STESCI currently includes over 100 researchers from 11 different countries, across Europe, North America, and South America. Its activities are spread over 51 sub-work packages, which tasks have been defined. However scientific issues remain to be debated in order to ensure optimized determination of stellar parameters with the accuracy required by the mission, yet unreached.
The adoption of the PLATO mission - last June - has speeded up the scientific preparation process. This workshop intend to gather STESCI members, with the aim of discussing and taking decisions about the best scientific options to derive stellar parameters with the uncertainties requested by the PLATO mission.
The PLATO science is one of the pivotal scientific projects in the context of INAF Piano Triennale 2017-2019. It is worth mentioning that a large fraction of the italian scientific community in the field of Stellar Astrophysics and Exoplanets is hugely involved in the PLATO core science.The national scientific community is strongly involved in the planning and construction – in collaboration with several engineering companies such as LEONARDO S.p.A., THALES, ALENIA SPACE, etc – of many optical and electronic components of the satellite.
The first part of the workshop will consist in presentations which will review the scientific issues and related tasks achieved since the previous workshop - held in Paris in May 2016. The decisions on the chosen scientific options are then to be definitely approved. In the second part, scientific presentations and discussions will take place about issues that still remain to be clarified and solved. Related actions and scientific work to be done will be decided.
