A cool stsr of this type radiates far more of its energy in the IR
than is the visible band. Hence it appears brighter in the CCD images
that records IR light only.

Our nearest neighbours - CN LEO (Wolf 359)

CN LEO is the 3rd closest system to Sol. The system consists of a red
dwarf of spectral class M6.0 with an estimated mass of only 9% that of
the Sun. Note how much brighter the M6.0 dwarf is in the IR rather
than V band and how well this is shown in this 120 second animated
exposure of IR and V band images.

Why would it be that much brighter?
