[4] It was identified as a white dwarf candidate from Gaia and virtual observatory data in 2018.

[5] In 2020 it was identified as a DBAZ: white dwarf, which means that it had helium, hydrogen and metal absorption lines.

The observations showed that the object had absorption due to hydrogen, helium, beryllium, oxygen, magnesium, silicon, calcium, titanium, chromium, manganese and iron.

[10] The presence of beryllium is thought to be the result of spallation of heavier elements (especially oxygen) on the surface of an icy dust belt around a giant planet.

The icy dust belts enriched in beryllium will then form exomoons, which might pollute white dwarf.
