PortraitLooktype

The look a star is drawn with: "supergiant" has a few huge convection cells, "giant" a dozen large ones, "sun-like" fine granulation, "red-dwarf" finer cells in a deeper red, "hot" a smooth disc (hot stars carry their energy by radiation and show no granulation we know of), and "fast-rotator" a smooth, flattened and gravity-darkened disc, drawn only for the stars with a measured shape.
