Abstract: |
The peculiar emission-line star MWC 137 with its extended optical nebula was recently classified as a B[e] supergiant. To study the spatial distribution of its circumstellar molecular gas on small and large scales, we obtained near-infrared and radio observations using SINFONI and APEX, respectively. We find that the hot CO gas is arranged in a moving clumpy ring and shell structures close to the star, while a cold CO envelope is encircling the borders of the optical nebula from South to West. |
