Description:
Carbon monoxide emission has been observed toward about 35 galactic reflection nebulae. The peaking of CO temperatures near the hotter stars indicates substantial local heating of the gas and dust by the embedded stars. Wide low-level emission wings are seen on several of the (C-12)O line profiles; these are most plausibly interpreted as due to cloud material accelerated by such processes as radiation pressure from the newborn stars.
