Abstract (from CDS):

In this paper, we present a dust emission map of the starless core TMC-1C taken at 2100 µm. Along with maps at 160, 450, 850, and 1200 µm, we study the dust emissivity spectral index from the (sub)millimeter spectral energy distribution, and find that it is close to the typically assumed value of β = 2. We also map the dust temperature and column density in TMC-1C, and find that at the position of the dust peak (AV∼ 50) the line-of-sight-averaged temperature is ∼7 K. Employing simple Monte Carlo modeling, we show that the data are consistent with a constant value for the emissivity spectral index over the whole map of TMC-1C.
