The near-UV: The true window on jet rotation
|Title:||The near-UV: The true window on jet rotation||Authors:||Coffey, Deirdre; Bacciotti, Francesca; Podio, Linda; Erkal, Jessica||Permanent link:||http://hdl.handle.net/10197/11157||Date:||1-Jan-2017||Online since:||2019-10-17T13:48:42Z||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.||Type of material:||Conference Publication||Publisher:||Società Astronomica Italiana||Journal:||Memorie della Societa Astronomica Italiana||Volume:||88||Issue:||4||Start page:||775||End page:||776||Copyright (published version):||2017 Società Astronomica Italiana||Keywords:||Jets; Outflows; Stars; Formation; RY Tau||Other versions:||http://sait.oat.ts.astro.it/MSAIt880417/
