  We present new ALMA Band 6 observations including the CO(2-1) line and 1.3 mm
continuum emission from the surroundings of the young stellar object DO Tauri.
The ALMA CO molecular data show three different series of rings at different
radial velocities. These rings have radii around 220 au and 800 au. We make
individual fits to the rings and note that their centers are aligned with DO
Tauri and its optical high-velocity jet. In addition, we notice that the
velocity of these structures increases with the separation from the young star.
We discuss the data under the hypothesis that the rings represent velocity cuts
through three outflowing shells that are possibly driven by a wide-angle wind,
dragging the environment material along a direction close to the line of sight
(i=19{\deg}). We estimate the dynamical ages, the mass, the momentum and the
energy of each individual outflow shell and those of the whole outflow. The
results are in agreement with those found in outflows from Class II sources. We
make a rough estimate for the size of the jet/wind launching region, which
needs to be of <15 au. We report the physical characteristics of DO Tauri's
disk continuum emission (almost face-on and with a projected major axis in the
north-south direction) and its velocity gradient orientation (north-south),
indicative of disk rotation for a 1-2 Msun central star. Finally we show an HST
[SII] image of the optical jet and report a measurement of its orientation in
the plane of the sky.
