We report the discovery in space of methyl silane, CH<sub>3</sub>SiH<sub>3</sub>, from observations of ten rotational transitions between 80 and 350 GHz (<i>J</i><sub>u</sub> from 4 to 16) with the IRAM 30 m radio telescope. The molecule was observed in the envelope of the C-star IRC +10216. The observed profiles and our models for the expected emission of methyl silane suggest that the it is formed in the inner zones of the circumstellar envelope, 1-40 <i>R</i><sub>*</sub>, with an abundance of ...[more]
