The study of Planck microwave temperature maps toward several nearby spiral edge-on galaxies had revealed frequency-independent temperature asymmetry detection of Doppler origin in their halos. The contribution of the dust component to that effect is studied in this paper, particularly for the case of the M31 galaxy, using the models of dust emission and the phenomenological profiles of the dark matter configurations. The obtained results are in accordance with those inferred from the microwave temperature asymmetry data, thus indicating the possible contribution of dust, among other radiation mechanisms, in revealing the dark halo parameters.
