Project title: COSTAR – COnstrain STellar physics using all-sky AsteRoseismology
Abstract:
Internal rotation, angular momentum transport, convection, and mass loss are among the least understood dynamical processes occurring in stars. How these processes interact and influence stellar structure and evolution is a major challenge in stellar physics. The only way to answer this fundamental question is through in-depth asteroseismology of solar-like stars spanning a wide range of fundamental properties, evolutionary stages, and galactic regions. 
The observed solar-like pulsating stars are currently around 40 thousands. Still, only about 100 of them have been characterized using in-depth asteroseismology. Given the large diversity of stars in the Galaxy, this sample is too small to provide a solid statistics. Besides, the detailed asteroseismic analysis is a very challenging problem that only few specialists in the world are able to perform. Existing techniques are limited in terms of both efficiency and automation. Within the next 10 years we will have to face the analysis of a million of stars, hence a strong effort urges to bridge this big gap.
Leveraging my forefront research in innovative approaches for asteroseismology, with the Bayesian code DIAMONDS as proof of concept, COSTAR will fully characterize the oscillations for 2 thousands solar-like pulsators using all-sky observations. By combining the new results with spectroscopic surveys (e.g. APOGEE) and astrometry (Gaia), COSTAR will thus develop new constraints that will bring stellar physics to a new level of understanding by taking into account the dynamics and their impact on the structure of stars throughout the stellar evolution.
COSTAR will also provide key stellar properties for improving galactic and planetary science. The success of this ambitious project requires the commitment of a competent scientist with the proper resources and the optimal time frame provided by the present call for proposals.
