... Examples might be: Stellar populations and metalicity in tidal debris and gas rich galaxies (large and small), inter-galactic HII regions, planetarynebula and stars associated with intra-cluster and intra-group atomic hydrogen. ...
... The first detailed study of this type of HCN transition was carried out for the Galactic proto-planetarynebula, CRL 618, by Thorwirth et al. (2003). ...

... However, as a result of this work, Lewis has found a new proto-planetarynebula with OH emission, 19386+0155, an object very like the prototypical example, 18095+2704, found at Arecibo 10 yr ago. ...

... to ~100 mJy, and were seen thereafter to decay exponentially. 18455+0448 has not been detectable since Dec 2000; moreover its red IR colors and the lack of any variability in its mainline masers suggest that it has indeed become a proto planetarynebula ...
