One unclear point: how would these planets form?
Stars go through the red giant phase before becoming white dwarves, so they will swallow all the planets close to the star. And blow away any remnants of the accretion disk.
- science4sail 2y agoMaybe the white dwarf captures a rogue planet? The planet doesn't need to be from the star's original accretion disk.
- cyberax 2y agoYou can't capture a body with only a two-body interaction. You need at least 3 bodies for that. I guess a star with a Jupiter-class planet that survived the red giant phase might qualify. But then the conditions will have to be just right for the captured planet to end up near the star.
