Taiwan-Russia Workshop on Polarization by Dust Grains
October 17, 2018
ASIAA R1107, AS/NTU Astronomy-Mathematics Building



Polarization of electromagnetic wave gives useful pieces of information on the physical condition in the circumstellar and interstellar media. The wavelength dependence of interstellar linear polarization, especially at optical and near-infrared wavelengths, in particular, provides evidence on grain size distribution, and on the grain alignment mechanism. Measurements of submillimeter polarization show a non-monotonic wavelength dependence, which is interpreted as a result of multiple dust components of differing compositions. Moreover, polarization can probe environments where extinction curves cannot be derived, e.g., in stellar winds and molecular clouds, where dust formation and growth occur.

By taking an occasion of a Russian collaborator's visit based on our MOST Taiwan-Russian bilateral collaboration project, we organize a workshop on polarization. This workshop is aimed at sharing our studies on polarization in an informal way to seek for future collaboration topics among us. The key questions are

  1. Which kind of dust physics is important for optical/near-infrared and submillimeter polarization?
  2. What kind of information can be extracted from polarization?
  3. Which kind of theoretical modeling will be necessary?


Everyone can apply for a talk. To keep sufficient time for discussion, the talk should be brief and summarizing what you have for the above three points (or something related) with a scope of possible collaboration items toward future.
