You may also see any of these images by clicking on the individual images. The "postage stamps" are arranged in a 3 × 3 matrix in order of wavelength: x-ray, blue, visual, red, near infrared pseudocolor, 12µm, 60µm, mm radio maps, and VLA cm radio maps. If a region is blank, then we offer no image at that wavelength, either because we have none or, in some cases, because there is no additional information in that image. After selecting an images, others of the matrix may be selected from a "clickable" colorbar beneath the image.
This heavily embedded cluster in the L1641 North region is the location of a powerful molecular outflow (Fukui et al. 1986). The existence of the group was discovered by Strom, Margulis and Strom (1989). It was further studied photometrically by Chen et al. (1993). An infrared spectroscopic study was done by Hodapp & Deane (1993). This group is extremely young as shown by the luminosity function (Strom, Strom & Merrill (1993) and the HR diagram (Allen, Strom & Strom (in preparation). Many of the stars in this cluster suffer enormous extinctions (>30 magnitudes in the visible). Few are seen at visible wavelengths.
