Fig. 2


The variations in grain alignment efficiency, as probed by the location of the peak in the polarization curve, is shown as a function of the relative angle between the magnetic field and radiation field anisotropy: Ψ (filled, black, diamonds). Also shown are the variations in the FIR ratio I60/I100 (open, red, diamonds). Both show a variation with Ψ. The change in the grain temperature can be understood in terms of the surface area facing the illuminating star, while the variations in λmax are consistent with predictions by RAT theory.
