Theory of Massive Star Formation

大质量恒星是宇宙中最亮的恒星。它们可以在我们的银河系和其他星系中被大量观测到。尽管有大量的观测数据，但我们对如此大质量恒星如何形成的理论知识还远远不够完整。理解大质量恒星形成的困难来自于这个问题的复杂性。例如，大质量恒星优先在邻近恒星通过流出物和强辐射反馈相互影响的星团中形成。这项提议的目的是建立一个综合的大质量恒星形成模型，该模型将整合这个问题的所有不同过程。到目前为止，我们对大质量恒星形成的理解来自不同的，只有松散联系的研究方向。对于拟议的项目，我们将把这些不同的领域结合起来。特别是，我们将包括新形成的大质量恒星产生的辐射、风和喷流的反馈。由于我们将在母体分子云的很大一部分内自我一致地追踪恒星形成，我们的结果还将包括星团中新形成的恒星之间相互作用的影响。我们还将跟踪恒星形成区域内的化学演化，我们将用观测数据来验证我们的模型。

Massive stars are the brightest stars in our Universe. They can be observed copiously in our own Milky Way and beyond it in other galaxies. Despite the substantial amount of observational data, our theoretical knowledge of how such massive stars form is far from being complete. Difficulties in understanding the formation of massive stars arise from the complexity of this problem. For instance, massive stars form preferentially in clusters where the neighbouring stars influence each other by outflows and strong radiation feedback. The aim of this proposal is to develop a comprehensive model of massive star formation which will integrate all the different processes of this issue.So far, our understanding of massive star formations comes from separate, only loosely connected, research directions. For the proposed projects we are going to combine these different areas. In particular we will include feedback from radiation, winds and jets produced by the newly formed massive star. As we will self-consistently trace star formation within a large fraction of the parent molecular cloud our results will also include the effect from interactions between the newly formed stars in the cluster. We will also keep track of the chemical evolution within the star-forming region which we will use to validate our models with observational data.
