A Journey across Hertzsprung-Russel diagram with 3D hydrodynamical simulations of cool stars

IPAG Seminar Room - IPAG

Nowadays, the development of the observational instruments is so high that became very sensitive to the details of stellar surface. The interpretation of the stellar surfaces images, the fundamental parameters, the stellar variability and the planet detection needs realist simulations of stellar convection. Three-­dimensional radiative hydrodynamics simulations of cool stars are essential to a proper and quantitative analysis of these observations. I will present how these simulations across the Hertzsprung-Russel diagram have been (and will be) crucial to prepare and interpret the spectrophotometric, interferometric, astrometric, and imaging observations.
