... Spectroscopy of white dwarf atmospheres has revealed metal pollution indicative of active accretion of rocky material (Gansicke et al. 2012), though the source of the debris - perhaps a disk of asteroids or tidally disrupted planets - is unknown. ... In addition, since typical white dwarfs are roughly Earth-sized, the transit of an Earth-sized planet can cause changes in brightness on the order of several tens of percent for durations on the order of one minute (Agol 2011). ...
