Long-lived Habitable Zones around White Dwarfs undergoing Neon-22 Distillation
Andrew Vanderburg, Antoine Bédard, Juliette C. Becker +1
White dwarf stars have attracted considerable attention in the past 15 years as hosts for potentially habitable planets, but their low luminosity and continuous cooling are major c…
