论文摘要
进入地球层的星际灰尘和气体为我们提供了有关地球层和局部星际培养基（LISM）的重要线索。我们从\ emph {intu}检测和吸收行数据中对本地星际云（LIC）的图片提出了对云的起源和演变具有重要意义的问题。 $^{60} $ fe在深海壳和南极雪地中的新检测为超新星在塑造局势中的作用提供了证据。我们讨论了我们在局部气泡内的LIC演变的模型，以及对超新星产生灰尘来源的可能解释。
Interstellar dust and gas that enter the heliosphere provide us with important clues about both the heliosphere and the local interstellar medium (LISM). The picture we have of the Local Interstellar Cloud (LIC) from both \emph{in situ} detections and absorption line data presents questions that have important implications for the origins and evolution of the cloud. New detections of $^{60}$Fe on Earth in deep sea crusts and Antarctic snow cores provide evidence for the role of supernovae in shaping the LISM. We discuss our models for the evolution of the LIC inside the Local Bubble and possible explanations for the source of the supernova produced dust.
