Extended He I Emission from DG Tau

We present spatially resolved 1.06-2.08 um IFU spectra towaard DG Tau obtained by AO assisted NIFS/GEMINI. We found that the He I 1.083 um emission is extended along the [Fe II] jet direction both blueshifted and redshifted side. The peak velocity is increasing from 0 to the [Fe II] jet velocity (~ 100 km/s) with the distance. The velocity width of He I emission is 2.35 times wider than that of [Fe II] 1.257 um. He I shows P-Cygni profile with blueshifted absorption and broad emission around the rest velocity. The spatial extension and broad velocity width are represented that the He I emission has dual origins both shock in collimated jet and stellar wind close to star
