The role of bipolar jets in the formation stars, and particular how they are launched, is still not well understood. We probe protostellar jet launching mechanism, via high resolution observations near-IR [FeII] 1.53,1.64 micron lines. consider from Classical T Tauri star, DO Tau, & investigate morphology kinematics close to using AO-assisted IFU GEMINI/NIFS. brighter, blue-shifted collimated q...
