摘要
An optical spectroscopic observation was made towards the circumstellar nebula of the supergiant VI Cyg 12, for the first time to the best of our knowledge. Several emission lines appear in the spectrum. Based on the spectra of the star and its circumstellar matter, as well as the IRAS and NVSS data, we conclude that VI Cyg 12 has an expanding shell with an expansion velocity 3100 km s(-1) due to strong stellar wind. It is an older star that possibly evolved from a very massive O-type star. The stellar wind and mass loss may take an important part in the evolution of this star.
