OPTICAL OUTFLOWS IN THE VICINITY OF THE SOUTHERN HERBIG AE BE STAR VDBH 65B/

Although there are a large number of Herbig-Haro (HH) outflows now kno wn from low mass pre-main sequence stars, i.e. classical T Tauri stars and embedded infrared sources of similar luminosity, this is not the case with their higher mass counterparts, the Herbig Ae/Be (HAeBe) sta rs. We report here the discovery of an outflow (HH140) from the HAeBe star vdBH 65b using the ESO Multi-Mode Instrument (EMMI) on the New Te chnology Telescope (NTT). A coronagraphic spot was employed to investi gate the area close to this star. At least 3 additional outflows (HH14 1, HH142 and HH143) were found in its vicinity. A similar search aroun d two other HAeBe stars (HD 101412 and HD 150193) showed no signs of o ptical outflows, nor for that matter any reflection nebulae, the prese nce of which is strictly required if a star is to be classified as a H AeBe star.
