Extended Data Table 1 Observed column density ratios of various species compared with disk models with solar C/O elemental ratio in the gas-phase

From: A rich hydrocarbon chemistry and high C to O ratio in the inner disk around a very low-mass star

  1. a. Assuming that the emission is either confined to the C2H2 highly optically thick component I or the optically thinner component II. The prominent features of the small hydrocarbons are associated with the extended component II only whereas the CO2 emission originates more likely from the thick component I (see main text). b. Woods & Willacy (2009). c. Walsh, Nomura & van Dishoeck (2015). d. Woods & Willacy (2007).
