角动量在恒星和行星的形成中起着至关重要的作用。人们早就注意到，分子云中的气体团需要将它们的比角动量减少6到7个数量级，才能参与像太阳这样的典型星星的形成。不同尺度和不同演化阶段的几个物理过程都可能导致角动量的损失。为了限制这些过程，更好地理解这种角动量的转移，在所有演化阶段和所有尺度的星星形成区域进行详细的观测普查和描述旋转是必要的。本文综述了近40年来在低质量星星形成区研究中取得的主要成果。它解决了分子云，星前和原恒星核心，拱盘和喷流的旋转的搜索和表征。阿尔马提供的观点进行了简要讨论。
Angular momentum plays a crucial role in the formation of stars and planets. It has long been noticed that parcels of gas in molecular clouds need to reduce their specific angular momentum by 6 to 7 orders of magnitude to participate in the building of a typical star like the Sun. Several physical processes on different scales and at different stages of evolution can contribute to this loss of angular momentum. In order to set constraints on these processes and better understand this transfer of angular momentum, a detailed observational census and characterization of rotation at all stages of evolution and over all scales of star forming regions is necessary. This review presents the main results obtained in low-mass star forming regions over the past four decades in this field of research. It addresses the search and characterization of rotation in molecular clouds, prestellar and protostellar cores, circumstellar disks, and jets. Perspectives offered by ALMA are briefly discussed.
