Dr. Andrea Chiavassa, CNRS, Observatoire de Nice is an ORIGINS guest (host: Prof. Rolf Kudritzki) and a well-known expert in the field of stellar and planetary atmospheres.
Nowadays, the development of the observational instruments is so high that they have become very sensitive to the details of stellar physics. The interpretation of the stellar surfaces images, the fundamental parameters, the stellar variability and the hosting planet detection & characterisation needs realistic simulations of stellar convection. In this context, 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 spectrophotometric, interferometric, astrometric, and imaging observations related to stellar and planetary applications.
