ALMA detects a radial disk wind in DG Tauri (Corrigendum)

Abstract

Following a production error, many arcsecond signs ( ) were replaced with degree signs ( • ) in the original version of this paper. Here we republish the paper in its entirety, correcting the errors.Article published by EDP Sciences C1, page 1 of 1 A&A 620, L1 (2018) ABSTRACTAims. 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 12 CO, 13 CO, and C 18 O 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.
