摘要: Using the results of our Hα interferometric observations and observational data on 21 cm CO lines, we have analyzed structure kinematics interstellar medium in extended vicinity star WR 137 supernova remnants CTB 87 G73.9+0.9. A shell with a radius up to 40′ observable optical lines has been discovered around 137. The high-velocity motions ionized hydrogen inside this can be interpreted as expansion gas swept out by wind at velocities 60 km/s. near emits systematic velocity VLSR ∼ 6–18 ofG73.9+0.9 55 km/s confirmed. toward remnant are ≃ −14…+14 An HI G73.9+0.9 detected VLSR≃−14…−8 very faint size about 20′ also detected. Evidence that is located Cygnus Arm presented.
