We report a detection of a radial velocity difference across the blue-shifted jet from RY Tau, the direction of which matches the CO disk rotation sense. Now, in 3 of 3 cases, the sense of the near-UV jet gradient matches the disk rotation sense, implying that we are indeed observing jet rotation. It seems the jet core, probed at near-UV wavelengths, is protected by the outer jet layers from kinematic contaminations, and thus represents the only true window on jet rotation.STAMPAenArticlehttp://sait.oat.ts.astro.it/MmSAI/88/PDF/775.pdfhttp://sait.oat.ts.astro.it/MSAIt880417/index.html2017MmSAI..88..775CFIS/05 - ASTRONOMIA E ASTROFISICA
