Dichroic extinction

WebThe dichroic extinction (i.e., the different extinction of the polarization components) of transmitted starlight through oriented dust particles is a well-documented phenomenon in the case of the 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, …
