Infalling streamline model for the DG Tau streamer. Top: Streamline model, plotted in green, on top of the moment-1 map of CS, spatially matching the observed streamer emission to the north (outlined in the green polygon). Bottom: Velocity components of CS taken from inside the green polygon plotted as a function of projected distance from the central young stellar object, with varying levels of kernel density estimation of the velocity plotted as filled contours. The contours start at 0.5σ and progressin steps of 0.5σ, where σ is from a bivariate normal distribution (see also Pineda et al. 2020). The streamline model, shown in green, describes most of the kinematics of the system in addition to the spatial match shown in the top panel. The main deviation is a small amount of blue-shifted emission in the streamer at a projected distance of ~100-150 au from the central young stellar object.
