Chemistry of Carbon-Chain Molecules around Massive Young Stellar Objects
[Abstract]
Carbon-chain molecules account for approximately 40% of the interstellar molecules, and they provide us with useful information about the star formation process. However, studies about carbon-chain molecules have been mainly conducted in low-mass star-forming regions. We now investigate the chemistry of carbon-chain molecules in high-mass star-forming regions. In this talk, I talk about the recent results with the single-dish telescopes, the Nobeyama 45-m telescope and the Green Bank 100-m telescope. We found that cyanopolyynes (HC2n+1N) are particularly abundant in high-mass star-forming regions, and the chemistry of carbon-chain molecules may be different from that in low-mass star-forming regions, namely warm carbon chain chemistry (WCCC).
