Direct estimation of electron density in the Orion Bar PDR from mm-wave carbon recombination lines ⋆

CONTEXT: A significant fraction of the molecular gas in star-forming regions is irradiated by stellar UV photons. In these environments, the electron density (n(e)) plays a critical role in the gas dynamics, chemistry, and collisional excitation of certain molecules. AIMS: We determine n(e) in the p...
