Abstract

Orion A is one of the nearest and best studied regions of star formation, the strongest CO source so far detected, and a particularly fruitful region in the search for new and ever more exotic molecules. A stellar wind, with genesis in some newly formed or forming star, is being power driven into a surrounding placental cloud. The resulting shocks lead to densities of order 1 x 10⁶ 1cm^-3 or higher, and gas kinetic temperatures T ~ 2000 K, causing excitation of H2 quadrupole emission in the near infrared and the higher rotational transitions of CO in the far-infrared.
