Webplained by dichroic extinction. Lucas et al. (2005) showed that strong circular polarization can occur with extinction, if grains are small dielectric par-ticles. Buschermohle et al. (2005) found a correla-tion between J−K color and circular polarization pc in the K-band in OMC1 (their Fig.7) which led them to favor dichroic extinction as the ... WebThe extinction due to dust is not equally effective at all wavelengths. The shorter the wavelength, the higher the extinction -- blue light is affected more strongly than red light. Therefore, stars behind a lot of dust look …

WebJan 28, 2009 · A simple relation between dichroic extinction, color excess, CP, and LP is derived. The observed correlation between the Stokes parameters and the color excess agrees with the derived relation, and suggests a major contribution of dichroic extinction to the production of CP in this region, indicating the wide existence of aligned grains.
