Extended Data Fig. 4: Colour-magnitude diagrams for b Cen (AB)b.
From: A wide-orbit giant planet in the high-mass b Centauri binary system

a, J2-J3 colour versus absolute J2 magnitude. b, K1-K2 colour versus absolute K1 magnitude. The planet b Cen (AB)b is plotted as a blue-green star, and follows the same colour trends as are generally observed for young planetary and substellar companions to stars, plotted as purple and black symbols with error bars. Symbols without error bars are young and field brown dwarfs.
