IRAS 04000+5052: a not so compact, not so metal-poor H II region.

Abstract (from CDS):

We present new observations of IRAS 04000+5052, a Galactic H II region that is associated with a young stellar cluster and is possibly located in the Perseus arm. We have found that contrary to previous claims, this object is not a compact metal-poor H II region. The electron density and chemical composition of the nebula are similar to those of normal H II regions of the Galactic disk. The radial velocity of the ionized gas coincides with that obtained from CO observations, indicating that the nebula is associated with a molecular cloud. Probably, the ionizing source of the H II region is a Herbig Be star of spectral type B0.5.
