Resumen

The peculiar emission-line star MWC 137 with its extended optical nebulawas recently classified as B[e] supergiant. To study the spatialdistribution of its circumstellar molecular gas on small and largescales, we obtained near-infrared and radio observations using SINFONIand APEX, respectively. We find that the hot CO gas is arranged inmoving clumpy ring and shell structures close to the star, while a coldCO envelope is encircling the borders of the optical nebula from thesouth to the west.
