A&A, 684, L25, 2024 A strong global magnetic field of young low-mass stars and a high accretion
rate are the necessary conditions for the formation of collimated outflows
(jets) from these objects. But it is still unclear whether these conditions are
also sufficient. We aim to check whether BP Tau, an actively accreting young
star with a strong magnetic field, has a jet. We carried out narrowband SII 672
nm imaging and spectroscopic observations of BP Tau and its vicinity. We find
that BP Tau is a source of a Herbig-Haro flow (assigned number HH 1181), which
includes two HH objects moving from the star in opposite directions and a
micro- (counter-) jet of ~ 1" projected length. The flow is oriented along
position angle $59 \pm 1$ degree.
