The V380 Ori Group: The 60 µ IRAS Image

This is the 60 µm 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 lying just south of the L1641N group. V380 Ori, the optically brightest object in this group has been recognized for a long time as a member of the Herbig Ae/Be star population (Herbig 1960), a young intermediate mass star. This star is the bright object illuminating the large reflection nebula (NGC 1999). The original H-H objects (Herbig 1951, Haro 1952) are also found in this field. They are the nebulous objects lying in the lower half of this field. An optical-infrared study of this region (Strom et al. 1985) was able to identify the powering source of the outflow, of which HH 1 & 2 are the visible manifestations, as the cm wavelength VLA source discovered by Pravdo et al. (1985). A water maser source, detected both by the VLA and IRAS also lies within this field as do numerous other extremely young objects as shown by the luminosity function derived for the region by Strom, Strom and Merrill in their infrared imaging study of L1641.

This far-infrared pseudocolor image was made by using a color map having white as the brightest, then blue, green, yellow, red and black at the faint end to display the intensity of each pixel. At this wavelength the strongest source seen in this field is a blend of the water maser source and the object, VLA 1, driving the HH 1 & 2 outflow.
