   Re: "habitable": That's part of what inspired the question. With all the   
   different types of life in SF, are there settings where someone put life   
   in a white dwarf system? For example, we have seen authors write about   
   native silicon-based life, native life in the atmospheres of gas giants,   
   etc.

   Agreed.
