Gómez de Castro, Ana Inés2023-06-202023-06-2019930004-637Xhttps://hdl.handle.net/20.500.14352/57561Subarcsecond spatial resolution images in the [S II] and [N II] + Halpha emission lines of the T Tauri star (TTS) CW Tau are presented. It is shown that CW Tau has a jet that extends up to 2.2'' (300 AU) from the star in the direction P.A. = 144-degrees. The jet emits strongly in [S II], and it is already collimated at 1.3'' (176 AU) from the star. The images also indicate that CW Tau is extended in the east-west direction and that the jet is slightly shifted to the east. This suggests that CW Tau may be a binary with the two components separated 0.20'' (28 AU). The observations are compared with the theoretical models proposed for the production of forbidden line emission regions (FLERs) and protostellar jets.engjournal articlehttp://adsabs.harvard.edu/abs/1993ApJ...412L..43Gopen access52Young stellar objectsFrance-Hawaii telescopehigh-resolution cameracircumstellar disksforbidden-lineStarsformationstarsindividual (cw-taurifm-tauriv773-tauri)pre-main-sequenceAstronomía (Matemáticas)21 Astronomía y Astrofísica
