We have carried out adaptive-optics assisted observations at the Subarutelescope, and have found 11 intrinsically polarized sources in the centralparsec of our Galaxy. They are selected from 318 point sources with Ks<15.5,and their interstellar polarizations are corrected using a Stokes Q/I - U/Idiagram. Considering brightness, near-infrared color excess, and the amount ofintrinsic polarization, two of them are good young stellar object (YSO)candidates with an age of ~10^5 yr. If they are genuine YSOs, their existenceprovides strong constraints on star formation mechanisms in this region. In theremaining sources, two are known as bow-shock sources in the Northern arm. Oneother is also located in the Northern arm and shows very similar properties,and thus likely to be a so far unknown bow-shock source. The origin of theintrinsic polarization of the other sources is as yet uncertain.
