[1] The system was initially identified as a cataclysmic variable on the basis of weak H-alpha emissions in the spectrum by the Sloan Digital Sky Survey (SDSS).

[2][4][5] After closer inspection the team of astronomers discovered oxygen and sulfur lines in the SDSS spectra.

The disk around the white dwarf is too large (~1-10 solar radii) to be formed by a small minor planet, which was tidally disrupted inside the Roche Radius.

The composition of the accreted material shows similarity to certain deeper layers of the ice giants in the solar system.

The team estimated that the planet around WD J0914+1914 will, over the span of about 350 million years, lose about 0.04 Neptune masses, a negligible amount.
