Abstract

ABSTRACT We present evidence that the nebular cocoon and bow-shock emission nebula putatively and recently reported as deriving from the 9th magnitude ‘runaway’ star HD 185806 is the previously discovered but obscure Planetary Nebula WHTZ 1 (Ra 7). It has a Gaia DR3 G∼16 blue ionizing star at its geometric centre. We present imagery, spectroscopy, other data and arguments to support that this emission source is a high excitation Planetary Nebula not a stellar wind bow shock.
