Old, Cold White Dwarf Star with Multiple Rings

Caption

The star, designated LSPM J0207+3331, is the oldest, coolest white dwarf known to be surrounded by a ring of dusty debris. This illustration depicts the ring with two distinct components, which scientists think best explains the system's infrared signal, and an asteroid broken up by the white dwarf's gravity.
