The dust must sublimate and will accrete onto the surface of the white dwarf, possibly through streamers of gas that follow the white dwarf's magnetic field lines. As in Saturn's rings, there might be streaks in the dust due to material that is darker than the surrounding dust, or perhaps caused by shadows of rocky bodies with sizes larger than the scale height of the disk. ...
