`Thermal' SiO radio line emission towards M-type AGB stars: a probe of circumstellar dust formation and dynamics

D. Gonzalez Delgado, H. Olofsson, F. Kerschbaum +3

An extensive radiative transfer analysis of circumstellar SiO `thermal' radio line emission from a large sample of M-type AGB stars has been performed. The sample contains 18 irreg…
