If life evolved on a planet with two suns, one emitting in the ultraviolet and one in the infrared, what light would that life evolve to see?
Let's say we have a binary star system, with a high mass star and a low mass, red dwarf star. High mass stars emit their light mainly in the ultraviolet while low mass stars emit mainly in the infrared. If a planet were orbiting the two stars and some happy aliens were living there, could the alien life evolve to see both ultraviolet and infrared light? Or are those wavelengths of light just too far apart on the light spectrum for eyes to evolve to see both?
It doesn't have to necessarily be a P type star system, it could maybe also be an S type star system with the planet orbiting just the red dwarf, but with the high mass star close by and shining on it. Something like this:
