Yes, I think Jonathan is correct. This may even have featured as one of the
objects on early Hubble slide collections. Do not confuse protoplanetary
disk (star and solar system being born) with proto-planetary nebula
(solar-type star evolving into a white dwarf).

The star just on its edge may be a foreground object, but some of these
(depending on inclination) show central stars (protostars). This one looks
too far off centre to be directly associated.
