Our dichroic plate beamsplitters … WebJHK s polarizations of point sources in M 17 show a wavelength dependence of the polarization of dichroic extinction in the general interstellar medium, indicating α ∼ 1.8 for the empirical relation P ∝ λ -α of interstellar polarization. The distribution of the polarization angle shows two peaks at 170° and 110°, indicating a non ...
WebFeb 17, 2024 · ABSTRACT. Magnetic fields (B) are an important factor controlling the star-formation process.The leading method to observe B orientation is to use polarized thermal emission from aligned dust grains. In dense environments such as protostellar cores, however, dust grains may be inefficiently aligned owing to strong gas randomizations, … 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.
