Image Details
Caption: Figure 6.
Ks 250 μm inverted color thumbnails with the positions of KN2-B (bottom) and KN3-A (top) overlaid as dashed circles. Scale is linear. Each circle has a radius of 5″, while the cross marks the position of R136. The scale bar in the bottom right corner is of 20″, or ≈5 pc at the distance to the LMC. The FWHM of each image is given by the solid circle above the scale bar. From the images, KN2-B and KN3-A are not visible at short wavelengths but have PAH emission associated with them in the 8 μm image (the PAH feature is at 8.6 μm and falls within the bandwidth). At 24 μm, emission likely arising from protostellar heating of the surroundings is visible at the position of KN2-B but not in KN3-A. At longer wavelengths of 100 and 160 μm from the Herschel imaging, both KN2-B and KN3-A are visible as point-like sources. However, at 250 μm, only KN2-B appears significant, with KN3-A extended. Also shown are the outermost contours for each of the KN clouds from Figure 2(a). In the 3.6 μm, the position of KN2-A is given by the arrow. The source is not bright at Ks or wavelengths >10 μm.
