Radially extended disk winds could be the key to unlocking how protoplanetary disks accrete and how planets form and migrate. A distinctive characteristic is their nested morphology of velocity and chemistry. Here we report James Webb Space Telescope near-infrared spectrograph spectro-imaging of four young stars with edge-on disks, three of which have already dispersed their natal envelopes. For each source, a fast collimated jet traced by [Fe ii] is nested inside a hollow cavity within wider lower-velocity H₂. In one case, a hollow structure is also seen in CO ro-vibrational (v = 1 → 0) emission but with a wider opening angle than the H₂, and both of those are nested inside an Atacama Large Millimeter Array CO (J = 2 → 1) cone with an even wider opening angle. This nested morphology, even for sources with no envelope, strongly supports theoretical predictions for wind-driven accretion and underscores the need for theoretical work to assess the role of winds in the formation and evolution of planetary systems.

径向延伸的盘风可能是解开原行星盘如何吸积以及行星如何形成和迁移的关键。一个显着的特征是它们的速度和化学嵌套形态。在这里，我们报告了詹姆斯韦伯太空望远镜对四颗带有边缘盘的年轻恒星的近红外光谱光谱成像，其中三颗已经分散了它们的本命膜。对于每个源，由 [Fe ii] 追踪的快速准直射流嵌套在较宽的低速 H₂ 内的空腔内。在一种情况下，在 CO 振动 （v = 1 → 0） 发射中也可以看到空心结构，但张角比 H₂ 大，并且两者都嵌套在阿塔卡马大型毫米波阵列 CO （J = 2 → 1） 锥体内，具有更宽的张角。这种嵌套形态，即使对于没有包络的来源，也有力地支持了对风驱动吸积的理论预测，并强调了需要进行理论工作来评估风在行星系统的形成和演化中的作用。
