Elusive Iron: Detection of the FeC Radical (X 3Δ i ) in the Envelope of IRC+10216

A new interstellar molecule, FeC ( X ^3 Δ _i ), has been identified in the circumstellar envelope of the carbon-rich asymptotic giant branch star IRC+10216. FeC is the second iron-bearing species conclusively observed in the interstellar medium, in addition to FeCN, also found in IRC+10216. The J =...
