Ionization fronts in RCW 107 (NGC 6164/5).
Abstract
Summary. The H ii region RCW 107 has been observed as part of a general spectroscopic survey of southern H ii regions. The ionization structure of the nebula confirms its association with HD 148937. The helium abundance of the nebulosity appears to be abnormally high. Photometric observations of HD 148937 in uvby and =3300 A, =80 A) are presented and fluxes within these wavebands have been determined. Key words: RCW 107 spectroscopy - helium abundance
