WD 1425+540 (G200-39) is a white dwarf that accreted an exocomet. This is evident from the pollution of the white dwarf atmosphere with metals, especially the pollution with nitrogen. WD 1425+540 is the first white dwarf with detected nitrogen. The white dwarf has a K-dwarf companion called G200-40, about 40 arcseconds away. The white dwarf nature of the object was discovered by Greenstein in 1974. The white dwarf is the prototype of the DBA spectral type that indicates both hydrogen and helium
