WD 0145+234

[3][5] Alternatively, the outburst around WD 0145+234 is explained with ongoing collisions between planetesimals inside the dusty debris disk around the white dwarf.

WD 0145+234 is however a single white dwarf and did not show any brightening in the optical images taken by CRTS and ASASSN.

[3] A follow-up study using the Spitzer Space Telescope found a decrease of the infrared brightness, beginning in late 2019.

The team studying WD 0145+234 with Spitzer concluded that the increase of brightness was not caused by the a tidal disruption of an exoasteroids, but by ongoing collisions in the disk around the white dwarf.

[6] Observations with NIRSpec released in a preprint in October 2023 showed that the debris disk is returning to its quiescent state.
