论文摘要
分子云中低质量恒星的形成涉及积聚磁盘和喷气机，它们具有广泛的天体物理感兴趣。积聚的星星代表了这些现象的最接近例子。恒星和行星的形成也密切相关，为我们自己的行星系统设定了起点。紫外（UV）光谱范围特别适合研究恒星形成，因为几乎所有相关过程都在与紫外线发射过程相关的温度下辐射，或者在紫外线中具有强大的观察性特征。在这篇综述中，我们描述了UV观察如何为增生过程，原球磁盘的物理特性以及喷气机和流出提供独特的诊断。
The formation of low-mass stars in molecular clouds involves accretion disks and jets, which are of broad astrophysical interest. Accreting stars represent the closest examples of these phenomena. Star and planet formation are also intimately connected, setting the starting point for planetary systems like our own. The ultraviolet (UV) spectral range is particularly suited to study star formation, because virtually all relevant processes radiate at temperatures associated with UV emission processes or have strong observational signatures in the UV. In this review, we describe how UV observations provide unique diagnostics for the accretion process, the physical properties of the protoplanetary disk, and jets and outflows.
