Abstract: In the shadow of a giant More than 100 planets and brown dwarfs have been discovered in orbits around stars like our Sun. When these stars evolve to become red giants they will easily engulf their companions: what happens then? The discovery of the first known close sub-stellar (brown dwarf) companion to a white dwarf suggests that, surprisingly, some of these companions will survive the interaction relatively intact.
