We have observed dense gas around the Very Low Luminosity Objects (VeLLOs) L1521F-IRS and IRAM 04191+1522 in carbon-chain and organic molecular lines with the Nobeyama 45 m telescope. Toward L1521F-IRS, carbon-chain lines of CH 3 CCH (5 0 ―4 0 ), C 4 H ( 17 / 2 ― 15 / 2 ), and C 3 H 2 (2 12 ―1 01 ) are 1.5-3.5 times stronger than those toward IRAM 04191+1522, and the abundances of the carbon-chain molecules toward L1521F-IRS are 2-5 times higher than those toward IRAM 04191+1522.

The Connection between Warm Carbon-chain Chemistry and Interstellar Irradiation of Star-forming Cores
Some observations of warm carbon-chain chemistry (WCCC) cores indicate that they are often located near the edges of molecular clouds. This finding may suggest that WCCC is promoted in star-formingExpand
