Magnetic Fields in Star Forming Regions - Near-Infrared and Submillimeter Approaches
In order to study the magnetic field structure in star forming regions on various scales, we have been conducting both near-infrared and submillimeter polarimetry toward nearby molecular clouds. The near-infrared approach is the polarimetry of either background or embedded sources in molecular clouds, useful to trace the magnetic field structure in the clouds and cloud cores. The submillimeter approach is the polarimetry of dust thermal emission from the circumstellar structure around young stellar objects, invaluable to trace the magnetic field in disks/envelops. In this paper, we present results of Kn (2.15 um) and H (1.65 um) band polarimetry of the ? Ophiuchi core obtained with an infrared array detector as well as results of 1100 and 800 um polarimetry of young stellar objects in a number of star forming regions.
