Objectives of the computing project
Parallelization of the LNAWENR software code. Development of the evolutive (stellar and pulsation) grid for stars with masses [0.8Msun-6.0Msun]. Development of the metaheuristic search algorithms and the pipe-line for stellar parameters determination in the previous grid Development of the Web-based portal for the LNAWENR pipe-line, in order to be used in the Kepler Space Mission by Kepler Asteroseismic Scientific Community (KASC) Application for ~ 1000 stars observed by diffrent Space Missions in the field: MOST, CoRoT, KEPLER.
Application's description
The development of an automated pipeline in the field of asteroseismology. The pipeline will include: - the development of an extensive evolutive (stellar and pulsation) grid for stars with masses [0.8Msun- 6.0Msun] and different metallicities; - the development of an automatic routine for modes extraction and modes ID from pulsating stars light curve; - the development of a fitting method (based on the already created grid) for each star, based on metaheuristic search algorithms in order to determine the absolute elements for each star (mass, radius, luminosity, effective temperature, gravity, metallicity, age, large and small separations).
The stars (>1000) are stars observed by different Space Missions in the field of asteroseismology (MOST, CoRoT and KEPLER SPace Missions).
Results expected in the allocation period
The development of the pipeline in the area of mode ID and integrate it with stellar modeling pipeline for a complete automation of the procedure. - Complete the treatment of surface effects and of the physical processes (e.g. convection, core overshooting, diffusion of chemical elements, etc.) through successful application of the prototype pipeline to space-based data on stars observed by CoRoT (use public data from the CoRoT satellite) and Kepler missions. - Extend the fitting method to include rotation velocity as an additional parameter and validate with data from CoRoT and Kepler missions and application of the prototype pipeline for asteroseismic data interpretation for Kepler mission (launch of the PLATO mission is planned for 2017/2018).
