T Tauri stars associated with Herbig-Haro objects and jets.

MUNDT R. and EISLOEFFEL J.

Abstract (from CDS):

We have obtained deep [S II] λλ6716, 6731 and continuum images of the five classical T Tauri stars (CTTSs) DP Tau, RW Aur, V536 Aql, LkHα 321, and V1331 Cyg. These CTTSs were selected for our imaging study because they either showed strong P Cygni absorptions in their spectra (LkHα 321, V1331 Cyg) or were known from long-slit spectroscopic studies to have bipolar jetlike outflows (DP Tau, RW Aur, V536 Aql). For the latter three objects, the spatial extent and structure of the outflows are studied here for the first time. In addition, LkHα 321 and V1331 Cyg were found to be associated with Herbig-Haro (HH) objects and/or HH jets. In four cases, the jets or outflows are bipolar, with the largest spatial extent seen in RW Aur (145"; 0.1 pc for d = 150 pc) and V1331 Cyg (360"; 1 pc for d = 550 pc). About 170" west of LkHα 321, we have serendipitously discovered a faint HH source, which we designate LkHα 321B.
