To date the search for habitable Earth-like planets has primarily focused on nuclear burning stars. I propose that this search should be expanded to cool white dwarf stars that have expended their nuclear fuel. I define the continuously habitable zone of white dwarfs and show that it extends from ≈0.005 to 0.02 AU for white dwarfs with masses from 0.4 to 0.9 M ☉, temperatures less than ≈104 K, and habitable durations of at least 3 Gyr. As they are similar in size to Earth, white dwarfs may be… CONTINUE READING
