HH137 and 138: discovering new knots and a molecular outflow with Gemini and APEX

Ferrero, L.V.; Cappa, C.E.; Gomez, M.

We present a multi-frequency study of HH 137 and HH 138 using Gemini images and APEX molecular line
data, as well as Spitzer images. Several 2.12 micron knots linked to HH137 are identified in the Gemini image. 12^CO(3-2),
13^CO(3-2), and C18^O(3-2) line data reveal the molecular counterpart of HH 137. Spitzer combined images suggest the
location of the exciting source of HH 137, almost coincident with a high-density molecular clump detected in C18^O. We
derive the main physical parameters of the molecular clump and the molecular outflow, and propose a simple scenario for the
whole complex.
