It's a shell star so I don't think this is a disk you're looking for but a disk nevertheless. Hopefully these can form at least minor planetary bodies from any ejected material that's not a gas.

This guy is actually pretty interesting--shell stars just mean that they were shown to have weak absorption features, which could mean they have some circumstellar gas. The presence of an IR excess for this object is good!

So that means that most shell stars of that apparent magnitude won't show up in WISE images?

I would have to double check, but my understanding is that previous searches of shell stars have showed a small fraction having any kind of signature of dust in the mid-IR. But that particular star is bright enough that it would show up in WISE even if it didn't have dust. However, we tried to only select WISE objects that were "extra" bright in WISE than you would expect for a typical star with no dust.
