Abstract Subarcsecond spatial resolution images in the forbidden S II and forbidden N II + H-alpha 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 arcsec (300 AU) from the star in the direction P.A. = 144 deg. The jet emits strongly in forbidden S II, and it is already collimated at 1.3 arcsec (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 arcsec (28 AU). The observations are compared with the theoretical models proposed for the production of forbidden line emission regions and protostellar jets.
