Scientific paper

The massive M supergiant Betelgeuse (alpha ori, M2 Iab) is one of the best studied stars in the sky. Its large angular diameter allows detailed spatially-resolved studies of the star and its circumstellar environment. Such studies can yield information on the physical processes that drive the observed large mass loss rates from these highly evolved stars. Here we report our CARMA (Combined Array for Research in Millimeter-wave Astronomy) 230 GHz (1.3 mm) radio interferometric observations of Betelgeuse that reveal the complex structure of its circumstellar environment.
