Star formation in Car I, a large PDR illuminated by the massive cluster Trumpler 14
The Car I photodissociation region (PDR) in NGC 3372 is illuminated by dozens of OB stars belonging to the massive open cluster Trumpler 14, whose nucleus is located at a projected distance of approximately 6 arcmin (4.5 pc) from its borders. We present the observed properties of the PDR as well as those of the very young stellar population embedded in it. These are based on ground-based optical and near-infrared imaging with narrow-band filters centered in several permitted and forbidden lines, including the 2.12 micron molecular hydrogen. Deep photometry in JHK bands is combined with IRAC/Spitzer and Herschell archived and published images to derive physical properties of the young and still forming stellar sources inside this PDR.
