Abstract

We present Atacama Large Millimetre/sub-millimetre Array observations of V883 Ori, an FU Ori object. We describe the molecular outflow and envelope of the system based on the 12CO and 13CO emissions, which together trace a bipolar molecular outflow. The C18O emission traces the rotational motion of the circumstellar disc. From the 12CO blueshifted emission, we estimate a wide-opening angle of ∼150 for the outflow cavities. Also, we find that the outflow is very slow (characteristic velocity of only 0.65 km s-1), which is unique for an FU Ori object. We calculate the kinematic properties of the outflow in the standard manner using the 12CO and 13CO emissions. In addition, we present a P Cygni profile observed in the high-resolution optical spectrum, evidence of a wind driven by the accretion and being the cause for the particular morphology of the outflows. We discuss the implications of our findings and the rise of these slow outflows during and/or after the formation of a rotationally supported disc.
