Extended Data Fig. 4: Possible indication for CH4 emission in the 7.64-7.77 μm range.
From: A rich hydrocarbon chemistry and high C to O ratio in the inner disk around a very low-mass star
CH4 emission could be present at 7.655 μm in addition to the many C2H2 lines in this region. The column density of CH4 is estimated assuming that the emission originates from component II (see main text, Table 1). The C2H2 model in purple corresponds to the component II for which the best-fit column density has been increased by a factor of 4 to better match the series of C2H2 lines in that specific spectral region.
