The «colours» are due to differences in the surface temperature
of starsw1: hotter stars emit most
of their

ultraviolet regions
of the electromagnetic spectrum, whereas cooler stars radiate at longer
wavelengths, in the visible red or infrared regions (see Mignone & Barnes, 2011a).
This large range
