标题： Local and Global Radiative Feedback from Population III Star Formation

摘要： 我们综述了近期关于理解在第三星族（Population III）恒星形成过程中可能起重要作用的辐射反馈过程的研究工作。 具体来说，我们研究了莱曼-瓦纳背景光对原始恒星早期形成的破坏作用，这种作用会延迟特定暗晕中的恒星形成，但不会完全抑制它。 我们还研究了来自邻近恒星系统的电离前缘（I-front）中光解和电离辐射对原始原恒星云形成的影响。 根据入射辐射场的强度和暗晕的中心密度，第三星族恒星的形成可能会被抑制、不受影响甚至增强。 理解这些以及其他效应对于模拟第三星族恒星的形成以及构建宇宙中最古老的几代星系至关重要。 显示英文摘要

摘要： We present an overview of recent work that focuses on understanding the radiative feedback processes that are potentially important during Population III star formation. Specifically, we examine the effect of the Lyman-Werner (photodissociating) background on the early stages of primordial star formation, which serves to delay the onset of star formation in a given halo but never suppresses it entirely. We also examine the effect that both photodissociating and ionizing radiation in I-fronts from nearby stellar systems have on the formation of primordial protostellar clouds. Depending on the strength of the incoming radiation field and the central density of the halos, Pop III star formation can be suppressed, unaffected, or even enhanced. Understanding these and other effects is crucial to modeling Population III star formation and to building the earliest generations of galaxies in the Universe.
