Scientific paper

Monochromatic observations in the O III and N II forbidden lines and interference observations in the H-alpha line of the emission nebula associated with the stars WR 134 and WR 135 are reported. The radial velocity field of this nebula is also investigated. On the basis of the morphology and kinematics of the nebula, the closed elliptical emission shell, including the nebula Anon MR 100, is ascribed to the effect of the stellar wind of WR 134. It is shown that WR 134 formed an envelope at the edge of the parent molecular cloud, which emits at a velocity of 5-7 km/s.
