The spectral energy distribution of the Carina nebula from far-infrared to radio wavelengths.

Abstract (from CDS):

Multi-wavelength observations are necessary for understanding the physical properties of astrophysical sources. In this paper, we use observations in the far-infrared to radio range to derive the spectral energy distribution (SED) of the Carina nebula. To do this, we carefully subtract the irregularly varying diffuse emission from the Galactic plane, which can be of the order of 10% of the nebula flux at these wavelengths. We find that the far-infrared SED can be modeled as emission from a dust population with a single temperature Td= (34.5+2.0_- 1.8_) K and with a spectral index of emissivity α = -1.37+0.09_- 0.08_. We also find a total infrared luminosity of the nebula of (7.4+2.5_- 1.4_)x106 Land, assuming a single temperature of the dust, a mass of the dust of (9500+4600_- 3500_) M.
