Abstract
Strip maps of (12)CO, (13)CO, and C(18)O J = 2-1 and J = 1-0 emissions from the Cep C dense core have been obtained to determine its density distribution and kinematic properties. Using large velocity gradient models to estimate gas conditions, we find that the H2 volume density ranges between 2500/cu cm at the core edge to 7000/cu cm at the central position. Absorption features are found in the (12)CO lines which are redshifted with respect to the cloud core velocities. Self-absorption is also identified in the profiles of (13)CO J = 2-1 emission but at velocities much closer to those of the central core of the line. Such a velocity structure denotes different kinematics and thermal conditions within several layers of material along the line of sight.
