行星状星云--红巨星喷出的外壳--为我们提供了最后一个质量损失阶段的历史，90%的恒星最初质量比太阳大。在这里，我们分析了詹姆斯韦伯太空望远镜（JWST）早期释放观测的行星状星云NGC 3132的图像。一个结构化的，扩展的氢晕围绕着一个电离的中央气泡，带有螺旋结构的印记，可能是由一个低质量的伴星围绕着中央星星旋转，大约40-60 Au。这些图像还揭示了中央星星的中红外过量，被解释为尘埃盘，这表明与另一个更近的伴星相互作用。包括先前已知的A型视伴星在内，NGC 3132行星状星云的前身至少是一个恒星四重奏。JWST图像使我们能够生成分子晕的照明，电离和流体动力学模型，展示了JWST调查复杂恒星流出的能力。此外，对A型视伴星的新测量使我们能够以极好的精度导出中心星星的前身质量值：2.86 ± 0.06 M质量。这些结果作为未来JWST行星状星云观测的探路者，为基本的天体物理过程提供了独特的见解，包括碰撞风和双星星星相互作用，对超新星和引力波系统的影响。
Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than the Sun. Here we analyse images of the planetary nebula NGC 3132 from the James Webb Space Telescope (JWST) Early Release Observations. A structured, extended hydrogen halo surrounding an ionized central bubble is imprinted with spiral structures, probably shaped by a low-mass companion orbiting the central star at about 40–60 au. The images also reveal a mid-infrared excess at the central star, interpreted as a dusty disk, which is indicative of an interaction with another closer companion. Including the previously known A-type visual companion, the progenitor of the NGC 3132 planetary nebula must have been at least a stellar quartet. The JWST images allow us to generate a model of the illumination, ionization and hydrodynamics of the molecular halo, demonstrating the power of JWST to investigate complex stellar outflows. Furthermore, new measurements of the A-type visual companion allow us to derive the value for the mass of the progenitor of a central star with excellent precision: 2.86 ± 0.06M⊙. These results serve as pathfinders for future JWST observations of planetary nebulae, providing unique insight into fundamental astrophysical processes including colliding winds and binary star interactions, with implications for supernovae and gravitational-wave systems.
