The higher the temperature of a star, the more light is emitted at all wavelengths. Although the peak temperature shifts in the blue direction the entire spectrum will rise in energy radiated.
Fomalhaut radiates in the visible spectrum about 5 times more energy than the Sun, even though its peak intensity is in the UV (330nm - 340nm). [I get 7x as much @ 400nm, 5x @ 500nm, and 3x @ 700nm. Does anyone have a simple equation for total energy output over a given portion of the spectrum?]
