Scientific paper

Although there are a large number of Herbig-Haro (HH) outflows now known 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) stars. 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 Technology Telescope (NTT). A coronagraphic spot was employed to investigate the area close to this star. At least 3 additional outflows (HH141, HH142 and HH143) were found in its vicinity. A similar search around two other HAeBe stars (HD 101412 and HD 150193) showed no signs of optical outflows, nor for that matter any reflection nebulae, the presence of which is strictly required if a star is to be classified as a HAeBe star.
