Detection of Interstellar HC5O in TMC-1 with the Green Bank Telescope

We report the detection of the carbon-chain radical HC5O for the first time in the interstellar medium toward the cold core TMC-1 using the 100 m Green Bank Telescope. We observe four hyperfine components of this radical in the rotational transition that originates from the fine structure level of i...
