Radiative hydrodynamics simulations of red supergiant stars. II. Simulations of convection on Betelgeuse match interferometric observations

This manuscript presents new comparisons of 3D radiative-hydrodynamic simulations and has derived intensity maps to a number of recent interferometric observations of Betelgeuse. This work improves our understanding of the surface properties, in particular the granulation pattern and the large-scale structure of Betelgeuse, as well as the utility and accuracy of the models.
