Using numerical simulations to determine the fraction of stars formed in clusters as a function of present-day field star populations

该项目将使用“EMP”（经验激励物理学）放大星系形成模拟来模拟星星集群的人口聚集。在EMP中包含冷ISM是这一研究领域的一个关键进展，将有助于确定环境如何塑造星团和其中恒星的形成和演化。具体而言，电磁脉冲使人们有可能准确地跟踪年轻的星星集群的演变，该项目将确定包括冷ISM是否影响（一）星星集群的诞生环境和初始条件，以及（二）年轻集群内原行星盘的预期寿命。电磁脉冲模拟将用于估计根据当今场星星属性的函数，在星团中形成的星星比例，并确定环境如何影响场星星、星团和星团中星星的形成。该项目将利用这些信息来确定哪些类型的行星可能已经形成并在不同的恒星周围生存，作为环境的函数，因此，在统计上最有可能承载生命。

This project will use the "EMP" (Empirically Motivated Physics) zoom-in galaxy formation simulations to model star cluster population assembly. The inclusion of the cold ISM in EMP is a key advance in this research area, and will help to determine how the environment shapes the formation and evolution of clusters and the stars within them. Specifically, EMP makes it possible to accurately track the evolution of young star clusters, and this project will determine if the inclusion of the cold ISM impacts (i) the birth environment and initial conditions of star clusters, and (ii) the expected lifetime of protoplanetary discs within young clusters. The EMP simulations will be used to estimate what fraction of stars formed in clusters as a function of present-day field star properties, and determine how the environment impacts the formation of field stars, clusters, and stars in clusters. The project will use this information to determine what types of planets could have formed and survived around different stars as a function of environment, and therefore, which are statistically most likely to host life.
