Cool, evolved stars PACS and SPIRE spectroscopy

At the end of their lives AGB stars are prolific producers of dust and gas. The details of this mass-loss process are still not understood very well. Herschel PACS and SPIRE...

渐近巨星分支恒星（Asymptotic Giant Branch, AGB）在演化末期会大量生成尘埃与气体。目前人们对这一质量损失（mass-loss）过程的细节仍未得到充分的认知。赫歇尔（Herschel）空间天文台的PACS（Photodetector Array Camera and Spectrometer）与SPIRE（Spectral and Photometric Imaging Receiver）...
