Abstract: We performed echelle spectropolarimetry of the T Tauri star RY Tauri at velocity resolution of ≈45 km s-1. We detected linear polarization of [OI]λ6300, Hα, NaD and OIλ7773 lines. The intrinsic polarization of [OI]λ6300 after subtraction of the foreground interstellar polarization was perpendicular to the disk long axis and parallel to the jet. Comparison of the [OI]λ6300 polarization with a simple scattering model suggests that the [OI]λ6300 emitting region is located within a few × 0.1 AU of the central star on a jet axis.
