Session 26 -- Molecular Cloud Structure and Energetics

Oral presentation, Wednesday, January 12, 10:15-11:45, Crystal Forum Room (Crystal City Marriott)

[26.05] CO Imaging of Molecular Clouds with Optical HII Regions

$^{12}$CO and $^{13}$CO J=1-0 images of molecular clouds associated with the optical HII regions S140, S155, and S235 made with the FCRAO 15 beam array receiver are presented. These images reveal a complex environment resulting from the interaction of the HII regions with the ambient cloud material. Cloud properties are compared to those derived from surveys of the Galactic Plane and other imaging studies of the molecular interstellar medium. These images emphasize that most of the kinetic energy is contained within the clump to clump motions on size scales greater than several pc.
