The spatial inhomogeneities on the surface of Betelgeuse revealed by modern interferometric observations are typically modelled as zero to three hot spots on a circular disk. While the surface structure appears to be generally consistent with an explanation as large-scale granular intensity fluctuations, the nature of the spots remains unclear.
The newly developed code COBOLD is now able to produce the first 3D radiation hydrodynamics simulations of a red supergiant, including realistic but simplified microphysics and non-local radiation transport.
The resulting models show giant convection cells, high spatial intensity fluctuations, and a surface pattern rather dissimilar to solar granulation. Some bright features over downdrafts might be interpreted as hot spots in low-resolution observations.
