The IRAS 08589-4714 star-forming region
  We present an analysis of the IRAS 08589-4714 star-forming region. This
region harbors candidate young stellar objects identified in the WISE and
Herschel images using color index criteria and spectral energy distributions
(SEDs). The SEDs of some of the infrared sources and the 70 microns radial
intensity profile of the brightest source (IRS 1) are modeled from Herschel
fluxes using the one-dimensional radiative transfer DUSTY code. For these
objects, we estimate the envelope masses, sizes, densities, and luminosities
which suggest that they are very young, massive and luminous objects at early
stages of the formation process. Color-color diagrams in the bands of WISE and
2MASS are used to identify potential young objects in the region. Those
identified in the bands of WISE would be contaminated by the emission of PAHs.
We use the emission distribution in the infrared at 70 and 160 microns, to
estimate the dust temperature gradient. This suggests that the nearby massive
star-forming region RCW 38, located ~ 10 pc of the IRAS source position may be
contributing to the photodissociation of the molecular gas and to the heating
of the interstellar dust in the environs of the IRAS source.
