This is the 60µm IRAS image.
You may also see images at other wavelengths by clicking on the colorbar at a point above any of the dashed arrows (which point to other regions of the spectrum at which images are available). The solid arrow shows the spectral region you are seeing now. This is not intended to be a linear scale in wavelength, but only a rough guide to the wavelength of the observation.
This group of stars is a small star forming aggregate in the southern part of the L1641 molecular cloud. It was initially studied by Cohen and Kuhi in 1979 in their monumental study of the then known pre-main-sequence stars in the local neighborhood. It has since been studied by Strom, Strom and Merrill in their infrared imaging study of L1641. Further work on this group was done by Lori Allen in her Ph.D. thesis.
This mid-infrared pseudocolor image was made using a color map having white is the brightest, then blue, green, yellow, red and black at the faint end, to display the intensity of each pixel. The only objects seen in this image are invisible at shorter wavelengths. The brightest object is deeply embedded in a molecular core between the two most southerly stars in the Cohen-Kuhi group.
