The carbon puzzle in observations

Volker Ossenlopf-Okada

Astrochemical models propose abundant atomic carbon in a transitional layer around molecular gas. Instead observations show bright [CI] in the clouds and weak emission outside. There seems to be significant variability but observational statistics is so far insufficient to address any causal relation. Cosmic rays may play a fundamental role.
