Reipurth 50: The Near Infrared Image

Re40 near infrared image

This is the near infrared 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.

Reipurth 50

This object was discovered by Reipurth (1985) in his survey of Nebulous objects in the Orion region. It was first discussed by Reipurth & Bally (1986) as the source of a powerful molecular outflow whose associated reflection nebulosity has only recently appeared in the blue lobe of the outflow. Polarization studies (Scarrott & Wolstencroft 1988) and near infrared imaging (Casali 1991) have demonstrated that the nebula is illuminated by the IRAS source. Recent longslit spectroscopic work (Strom & Strom 1993) has demonstrated that Re 50 is probably a heavily embedded FU Ori object (Hartmann, Kenyon & Hartigan 1993) currently in outburst.

This near infrared pseudocolor image was made by combining the images at J (blue), H (green) and K (red). The shortest wavelength image is mapped into blue and the longest into red, producing the image that you see.
