Invited Presentation
Infrared Polarimetric Studies toward Star and Planet Forming Regions
What is the origin of life on Earth? Where did life on Earth come from? Research into star and planet formation throws new light on these questions and arouses public curiosity. In this presentation, we show our recent circular and linear polarimetric studies of star forming regions in wide-fields. Our first systematic wide-field (~8 arcmin) circular and linear polarization survey of star forming regions with IRSF/SIRPOL has resulted in discovery of ubiquity of extended circular polarization in nebulae. The degrees and extents of the circular polarization have a clear trend with the masses of the forming stars.
