Abstract
By using a detailed radiative transfer model, we show that the observe d far-infrared spectrum of the Bok globule Barnard 335 can be explaine d by dust emission whose only energy source is the interstellar radiat ion field. The anomalous excess radiation observed around 60 mum in B3 35 and other globules can be accounted for by a 'nonconventional' dust component, the very small grains already proposed for other celestial objects.
