Re: With a little bit of imagination...
White dwarfs are extremely hot bodies and emit their most of their energy in the blue end of the visible if not UV. They are stars at the end of the fusion burning sequence. About 15,000 K whereas our sun is about 5,000 K, Brown dwarfs now ARE I think what your talking about.
Bodies with not enough mass to accomplish H-H fusion on any meaningful
scale, making them in a sense failed stars.
