Dynamically active planetary systems orbit a significant fraction of white dwarf stars. These stars often exhibit surface metals accreted from debris disks. However, the full journey of a planetesimal from star-grazing orbit to final dissolution in the host star is poorly understood. In a new paper in the Astrophysical Journal Letters, astronomers report the discovery that the cool metal-polluted star WD 0816-310 has cannibalized heavy elements from...
