Observations have mapped the distribution of gas velocities in a circumstellar disk wind for the first time. The high spatial resolution required for these observations is achieved by measuring the maser emission of water molecules. These findings validate theoretical predictions from the 1980s and can be replicated by modern numerical models.

This article presents the original analytical idea of the magnetohydrodynamic physics of the launching, acceleration, and collimation of disk winds and jets.
Pudritz, R. E. & Norman, C. A. Centrifugally driven winds from contracting molecular disks. Astrophys. J. 274, 677–697 (1983). This article applies the theory to stars forming via disk accretion.
Kölligan, A. & Kuiper, R. Jets and outflows of massive protostars. From cloud collapse to jet launching and cloud dispersal. Astron. Astrophys. 620, A182 (2018). This article presents numerical models of forming massive stars and compares them with the analytical theory.

Lee, C. F. & Ho, P. T. P. A rotating protostellar jet launched from the innermost disk of HH 212. Nat. Astron. 1, 0152 (2017). This article presents one of the clearest examples of jet rotation, which was the best evidence for the existence of a disk wind prior to our findings.
