论文摘要
在过去的十年中，在观测和理论方面，对寒冷星际培养基中多个尺度的结构发展的研究已经历了迅速的扩展。在广泛的物理尺度上的（亚）毫米波长的光谱线研究为星形形成区域中致密气体的运动学提供了独特的探针，并通过分子云的分子云配合物的柱柱密度结构的广泛，高动态范围的粉尘连续性冲动得到了补充，而尘埃极化图具有高光谱的磁性领域。这伴随着越来越复杂的数值模拟，包括新物理学（例如，超新星驾驶，宇宙射线，非理想的磁磁性 - 氢动力学，辐射压力）和新技术，例如允许多尺度研究的变焦模拟。综上所述，这些新数据强调了所有尺度上致密结构的各向异性生长，从巨大的ISM气泡通过$ \ sim $ \ sim $ 50-100 pc缩放的巨大ISM气泡通过parsec尺度的分子细丝量表，降低到$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ 1000 au Protostellar disk。结合了观察和理论，我们为这些结构的形成和演变提供了连贯的图片，并为恒星和磁盘形成的初始条件和早期阶段综合了一个全面的物理场景。
The study of the development of structures on multiple scales in the cold interstellar medium has experienced rapid expansion in the past decade, on both the observational and the theoretical front. Spectral line studies at (sub-)millimeter wavelengths over a wide range of physical scales have provided unique probes of the kinematics of dense gas in star-forming regions, and have been complemented by extensive, high dynamic range dust continuum surveys of the column density structure of molecular cloud complexes, while dust polarization maps have highlighted the role of magnetic fields. This has been accompanied by increasingly sophisticated numerical simulations including new physics (e.g., supernova driving, cosmic rays, non-ideal magneto-hydrodynamics, radiation pressure) and new techniques such as zoom-in simulations allowing multi-scale studies. Taken together, these new data have emphasized the anisotropic growth of dense structures on all scales, from giant ISM bubbles driven by stellar feedback on $\sim$50-100 pc scales through parsec-scale molecular filaments down to $<$0.1 pc dense cores and $<$1000 au protostellar disks. Combining observations and theory, we present a coherent picture for the formation and evolution of these structures and synthesize a comprehensive physical scenario for the initial conditions and early stages of star and disk formation.
