论文摘要
在新生儿周围检测外球星和增生盘的发现，已经催生了新的想法和模型，说明了我们的太阳系如何形成和进化。作为地质深度探针的陨石可以为这些模型提供基础真理。特别是，陨石中稳定的同位素异常最近已成为早期太阳系材料流的关键示踪剂，从而使宇宙学家能够建立“行星同位素家谱”。尽管不完整，但这个概念从根本提出了我们对太阳系演变的理解，从太阳的父母分子云的崩溃到行星的积聚。
The detection of exoplanets and accretion disks around newborn stars has spawned new ideas and models of how our Solar System formed and evolved. Meteorites as probes of geologic deep time can provide ground truth to these models. In particular, stable isotope anomalies in meteorites have recently emerged as key tracers of material flow in the early Solar System, allowing cosmochemists to establish a "planetary isotopic genealogy". Although not complete, this concept substantially advanced our understanding of Solar System evolution, from the collapse of the Sun's parental molecular cloud to the accretion of the planets.
