Galactic ring nebulae associated with Wolf-rayet stars. III. Region-type nebulae.
Abstract
Fabry-Perot data for five galactic ring nebulae associated with Wolf-Rayet stars have been obtained. The amount of turbulence in these nebulae is comparable to that in an ordinary H II region. It seems that these nebulae are only being illuminated by the central star. There is no evidence that these nebulae are formed from either material ejected from the stars or by stellar winds interacting with the interstellar medium.
