Metal-rich stars accumulate their metals from previous generations of stars, and so contain the history of their galaxy. By studying these stars we can gain valuable insights into how metals change the formation and evolution of stars, and explain the extraordinary massive star populations observed in the metal-rich region of our own galaxy. Observations of metal-rich regions have shown that stars hosting giant planets are generally metal-rich, which has triggered further observations of metal-rich stars. This has led to the discovery of new exoplanets, and advances in the study of planet formation and the late chemical evolution of galaxies. This book covers many aspects, from spectral line formation to stellar formation and evolution in high metallicity regimes. It is invaluable to researchers and graduate students in stellar evolution, extragalactic astronomy, and planet formation.

無人機技術主導著未來的飛行領域，其安全性、高效率和成本優勢在軍事應用、商用和政府職能方面都有著良好的應用前景。儘管無人機技術存在眾多優點，但也存在一定的安全隱患，例如恐怖分子、犯罪分子等非法使用無人機是目前亟需解決的一個安全問題。本書主要研究不同種類無人機的隱患，重點關注恐怖分子和犯罪分子對無人機的非法使用；介紹無人機的技術發展，並對現有的無人機進行了概述，包括其分類及主要組件；探討反無人機技術和系統，詳細介紹各種傳感器並給出目前市面上可用的監測系統的實例；檢驗並闡釋反無人機的策略，介紹監管框架、反無人機訓練和相關研究分析，旨在推動無人機及無人機探測技術的發展。本書可為相關專業人士和實踐者提供了專業的指導和建議。
