内容記述The ionized zone surrounding MWC 349 has been resolved using the VLA. On the basis of a radio continuum map, it is concluded that there is a physical interaction between the two stellar components of MWC 349, and that the system is therefore a binary. The B component can be classified as a B0 III star, yielding a distance of about 1.2 kpc for the binary. The low ratio of infrared to short-wavelength luminosity in the A component suggests a circumstellar dusty region of special geometry. It is proposed that an appreciable dust and gas disk surrounds the star, modifying the symmetry of its H II region, and yielding the low infrared luminosity and perhaps its extra circumstellar extinction.
