Title: | The near-UV: the true window on jet rotation | Authors: | Coffey, D. BACCIOTTI, Francesca PODIO, LINDA Erkal, J. |
Issue Date: | 2017 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Number: | 88 | First Page: | 775 | Abstract: | High resolution observations of jet rotation in newly forming stars have the potential to support theories of magneto-centrifugal jet launching. 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. | URI: | http://hdl.handle.net/20.500.12386/27126 | URL: | http://sait.oat.ts.astro.it/MmSAI/88/PDF/775.pdf http://sait.oat.ts.astro.it/MSAIt880417/index.html |
