Scientific paper

Thorne-Zytkow objects (TZO) are likely to have high mass loss rates, such that their optical photospheres are obscured by a dusty envelope. Indentification of massive TZO through abundance anomalies associated with the irp process in the core is more likely to be possible by observing molecular transitions in the 4-8 μm region and at mm wavelengths than in the optical. A promising molecule is SiO, with anomalously high abundances predicted for ^29^SiO and ^30^SiO. An upper limit for ^30^SiO is reported for the unusually bright galactic center SiO maser OH359.762+0.120.
