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.

这个项目将使用“EMP”(经验激励物理)放大星系形成模拟来模拟星团的聚集。将冷的ISM包括在EMP中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系团和其中的恒星的形成和演化。具体地说，电磁脉冲使精确跟踪年轻星团的演化成为可能，该项目将确定是否包括冷的ISM影响(I)星团的诞生环境和初始条件，以及(Ii)年轻星团内原行星盘的预期寿命。电磁脉冲模拟将被用来估计星团中形成的恒星的比例作为当今场星属性的函数，并确定环境如何影响场星、星团和星团中的恒星的形成。该项目将利用这些信息来确定哪些类型的行星可能在不同的恒星周围形成并存活下来，这是环境的函数，因此，从统计上讲，哪些行星最有可能拥有生命。
