ESA/AURA astronomer at STScI. Opinions my own. I study exoplanets and disks around stars.
Got it too. I thought it was the institutional phish test

The IR photometry is consistent with a 6 Mjup planet or a dust disk located at 0.02 au, 4-5x further than most other debris disks are believed to be located. So, many questions remain for follow-up!

The white dwarf barely shows a detection of Ca at 3934 Angstroms in 1999 and 2025, which is indicative that it is actively accreting dust. However, the accretion rate inferred is extremely low, making it hard to explain the IR excess from a typical dust disk one sees around white dwarfs.
