29SiO and 30SiO J=1--0 maser signatures in Galactic AGB stars: the impact of third dredge up and turbulence velocity

M. O. Lewis, L. O. Sjouwerman, Y. M. Pihlström +3

J=1--0 SiO masers at 43 GHz have a well-established distinctive signature in asymptotic giant branch (AGB) stars. 28SiO transitions typically dominate these spectra with the v=1 an…
