Space as a spectroscopic laboratory: High-resolution spectroscopy of the [${}^{13}$C II] hyperfine structure with SOFIA/upGREAT

S. Kabanovic, V. Ossenkopf-Okada, S. Schlemmer +13

The paper uses high‑resolution SOFIA/upGREAT observations of the 158 µm [13C II] line to directly measure its hyperfine splitting and determine the magnetic‑dipole hyperfine consta…
