Authors: Desrousseaux, Benjamin; Lique, Francois; Goicoechea, Javier R.; Quintas-Sanchez, Ernesto; Dawes, Richard Contribution: Article Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2020/12/21 DOI: 10.1051/0004-6361/202039823 Abstract: The detection of CF+ in interstellar clouds potentially allows astronomers to infer the elemental fluorine abundance and the ionization fraction in ultraviolet-illuminated molecular gas. Because local thermodynamic equilibrium (LTE) conditions are hardly [...]
