Astronomy Observation - stellar astronomy

与JWST一起在本地组进行银河系考古学。演化中的恒星群在红外线中发出明亮的光芒，是追踪本地星系中过去星星形成的绝佳示踪剂。此外，恒星生命周期的AGB阶段通过以尘埃形式的质量损失对其周围环境的化学富集做出了巨大贡献。然而，正是这种机制使得我们很难用现有的任何仪器来观测这些恒星。最近JWST的成功发射为我们提供了一个研究这些难以捉摸的恒星的绝佳机会。这个项目保证了JWST在第一个周期的时间，我们将用它来观察四个局部宇宙物体，并进一步了解进化种群中的尘埃周期。

Galactic archaeology in the local group with JWST. Evolved stellar populations shine brightly in the infrared and are an excellent tracer for past star formation in local galaxies. In addition, the AGB stage of stars life cycle contributes greatly to the chemical enrichment of its surroundings through mass loss in the form of dust. However, this very mechanism makes observing these stars very difficult with any current instruments available to us. The recent successful launch of JWST gives us an excellent opportunity to study these elusive stars. This project has guaranteed time on JWST in the first cycle which we will use to look at four local universe objects and gain further insight to the dust cycle in the evolved populations.
