Scientific paper

Direct imaging, photometry, and optical and mm-spectroscopy of We 21
shows that this object is a subluminous WN 8 star with an absolute
magnitude near Mv = -1.3. It is the central star of a low-excitation,
possibly nitrogen-rich planetary nebula, which interacts with dense
interstellar material of the inner Carina arm.
