JHKs and GLIMPSE photometry of RCW 120

We wish to take advantage of the very simple morphology of RCW 120 - a perfect bubble - to understand the mechanisms triggering star formation around an HII region and to establish what kind of stars are formed there. We present 870um observations of RCW 120, obtained with the APEX-LABOCA camera.

These show the distribution of cold dust, and thus of neutral material. We use Spitzer-MIPS observations at 24um and 70um to detect the young stellar objects present in this region and to estimate their evolutionary stages.
