dc.description.abstract | Aims. We aim to use the high spatial resolution of the Atacama Large Millimeter/submillimeter Array (ALMA) to map the flow pattern of molecular gas near DG Tauri and its disk, a young stellar object driving a jet and a molecular outflow. Methods. We use observations from ALMA in the J = 2-1 transition of 12CO, 13CO, and C 18O to study the Keplerian disk of DG Tauri and outflows that may be related to the disk and the jet. Results. We find a new wind component flowing radially at a steep angle (≈ 25° from the vertical) above the disk with a velocity of ≈ 3.1 km s -1. It continues the trend of decreasing velocity for increasing distance from the jet axis ("onion-like velocity structure"). Conclusions. The new component is located close to the protostellar disk surface and may be related to photoevaporative winds. | en |
