WD 0010+28
(Preview)
Can Planets Be Rejuvenated Around Dead Stars? How might a planet reclaim the essence of its youth? Years ago, astronomers predicted that some massive, Jupiter-like planets might accumulate mass from their dying stars. As stars like our sun age, they puff up into red giants and then gradually lose a...
