Three-dimensional hydrodynamical simulations of red giant stars: Semi-global models for interpreting interferometric observations

Chiavassa, A; Collet, Remo; Casagrande, Luca; Asplund, Martin

Description

Context. Theoretical predictions from models of red giant branch stars are a valuable tool for various applications in astrophysics ranging from galactic chemical evolution to studies of exoplanetary systems. Aims. We use the radiative transfer code Optim3D and realistic 3D radiative-hydrodynamical (RHD) surface convection simulations of red giants to explore the impact of granulation on interferometric observables. We assess how 3D simulations of surface convection can be validated against...[Show more]
