CH+ in Shocks, Cloud-Intercloud Interfaces, and Dense Photodissociation Regions
Published online by Cambridge University Press: 07 August 2017
Extract
Substantial CH+ abundances are found in at least three types of environment (Lambert and Danks, 1985): atomic regions with little H2, N(CH+) ~ 1012 cm−2; diffuse clouds such as that toward ζ Oph, N(CH+) ~ 1013 cm−2; reddened (2 ≲ Av ≲ 4) lines of sight to bright stars N(CH+) ~ 1014 cm−2. We explore the view that several different mechanisms operate.
