ALMA reveals a large structured disk and nested rotating outflows in DG Tauri B

Original language description

We present Atacama Large Millimeter Array (ALMA) Band 6 observations at 14-20 au spatial resolution of the disk and CO(2-1) outflow around the Class I protostar DG Tau B in Taurus. The disk is very large, both in dust continuum (R-eff,R- 95% = 174 au) and CO (R-CO = 700 au). It shows Keplerian rotation around a 1.1 +/- 0.2 M-circle dot central star and two dust emission bumps at r = 62 and 135 au. These results confirm that large structured disks can form at an early stage where residual infall is still ongoing.
