Detection of the S(1) Rotational Line of H-2 toward IRC+10216: A Simultaneous Measurement of the Mass-loss Rate and CO Abundance
Authors: Fonfria, J. P.; DeWitt, C. N.; Montiel, E. J.; Cernicharo, J.; Richter, M. J. Journal: ASTROPHYSICAL JOURNAL LETTERS Publication date: 2022/03/01 DOI: 10.3847/2041-8213/ac5a58 Abstract: We report the first detection of the S(1) pure rotational line of ortho-H-2 at 17.04 mu m in an asymptotic giant branch star, using observations of IRC+10216 with the Echelon-cross-echelle [...]
