Three-dimensional views of the photosphere of Betelgeuse on December, 20 2013. On the left, the explored region has been radially stretched to ten times its probable size to better see the inferred vertical structures. The darkest regions have been made transparent. In the center, we show the star with the spatial scale that we consider closest to reality. In both images, a central yellow sphere marks the lower bound of our images, roughly corresponding to log τ = 1, if this opacity were to be a smooth surface. On the right, radial velocities scaling from –60 to +60 km s⁻¹; blue is rising plasma.
