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.
