LSPM J0207+3331 is a cold and old white dwarf that hosts a circumstellar disk, located 145 light-years from Earth.

The presence of the Paschen Beta-Line in a near-infrared spectrum from the Keck telescope helped to determine that the atmosphere of LSPM J0207 is dominated by hydrogen (spectral type DA).

This suggests that the outer disk formed relative recently from a tidal disruption of such a small body.

If this outer disk is confirmed, it would be the first known dusty white dwarf with a two-component ring system.
