| Abstract: |
With the IRAM radio telescope we have observed rotational transitions of HCN(1–0), CS(3–2), CS(5–4), and SiO(3–2) in two carbon stars with OH maser emission detected towards them: IRAS 04130+3918 and IRAS 06238 +0904. We present results of modelling the molecular emissions for the latter object. Physical parameters of the envelope were established from a model of the spectral energy distribution. A chemical model was developed for the envelope assuming that it is a genuine carbon star. The observed emissions were fitted with a non-LTE code. We conclude that the observed abundance of the SiO molecule may be explained by the gas-phase chemistry in the envelope. |
