Elusive Iron: Detection of the FeC Radical (X<sup>3</sup>Δ<sub>i</sub>) in the Envelope of IRC+10216
Astrophys. J. Lett. 958, Art. No. L6 (2023).
Dedicated observations of CW Leonis with the ARO SMT as well as observations from a line survey at 2 mm with the ARO 12 m dish at Kitt Peak in the regions of the 3Δ3, J“ = 5, 4, and 3 transitions of FeC. The derived column density is nearly the same as for FeCN.
