论文摘要
近年来，在识别宇宙射线在星形环境中的作用方面发生了令人兴奋的发展。从无线电到红外波长和理论建模的观察结果表明，低能宇宙射线（<1 TEV）在塑造星际介质的化学丰富性方面起着基本作用，确定了分子云的动态演化。在这篇综述中，我们在一致的图片中总结了通过观测和宇宙射线传播和产生的理论模型获得的主要结果，从最小的Protostars和Internelar Discs到年轻的恒星簇，再到银河系和外层面尺度。我们还讨论了将在不久的将来探索的新领域，这要归功于新一代工具，例如：CTA，以$γ$ - 高质量原始恒星的排放； SKA和前体，用于在不同尺度上发射的同步子发射；以及ELT/HIRES，JWST和ARIEL，以实现宇宙射线对超球门气氛和宜居性的影响。
In recent years, exciting developments have taken place in the identification of the role of cosmic rays in star-forming environments. Observations from radio to infrared wavelengths and theoretical modelling have shown that low-energy cosmic rays (<1 TeV) play a fundamental role in shaping the chemical richness of the interstellar medium, determining the dynamical evolution of molecular clouds. In this review we summarise in a coherent picture the main results obtained by observations and by theoretical models of propagation and generation of cosmic rays, from the smallest scales of protostars and circumstellar discs, to young stellar clusters, up to Galactic and extragalactic scales. We also discuss the new fields that will be explored in the near future thanks to new generation instruments, such as: CTA, for the $γ$-ray emission from high-mass protostars; SKA and precursors, for the synchrotron emission at different scales; and ELT/HIRES, JWST, and ARIEL, for the impact of cosmic rays on exoplanetary atmospheres and habitability.
