Recycling planets around white dwarfs

Post by Lazarus on 15th May 2018, 5:58 pm

What happens to tidally-destroyed planets around white dwarf stars? It seems it might be possible for the debris disc to re-accrete into new planets close to the star, which might be a pathway for getting terrestrial planets into the habitable zone. Maybe.
