| Research Abstract |
Extensive near-infrared polarimetric observations have been conducted to reveal the magnetic field structure associated with dense gas clump, which is a parent object of newly formed stars. We discovered a dense gas clump associated with distorted magnetic field structure reminiscent of "hourglass". The structure is an indicative of frozen-in uniform magnetic fields dragged by gravitationally contracting medium. The dense gas clumps with distorted magnetic fields should be in the very early stage of star formation, and are invaluable samples for the determination of initial physical condition of star formation.
