Although they're no longer performing fusion in their cores, they're still hot and putting out radiation that could support life. A new paper calculates that a white dwarf could support planets in a new habitable zone for 7 billion years, providing the right temperature and radiation to support a biosphere. They're also small and dim, which makes it easier to study planets in orbit around them for potential biosignatures.
