The mass function of stars at birth

这个项目旨在回答围绕恒星诞生的三个问题：是什么决定了恒星在我们银河系出生时的质量，即所谓的初始质量函数(IMF)？国际货币基金组织如何依赖于形成恒星的气体云的物理性质？流出和喷流使平均恒星质量减少了多少，并决定了IMF的形状？预计该项目将产生迄今为止与星系形成和演化相关的最逼真的星团形成计算机模拟。这些模拟也可能为理解系外行星的形成提供初始条件。

This project aims to answer three questions surrounding the birth of stars: What determines the mass of stars when they are born in our Galaxy, the so-called Initial Mass Function (IMF)? How does the IMF depend on the physical properties of the gas cloud in which stars form? By what amount do outflows and jets reduce the mean stellar mass and determine the shape of the IMF? It is expected that the project will generate the most realistic computer simulations of the formation of star clusters to date, with relevance to galaxy formation and evolution. The simulations may also provide the initial conditions for understanding exo-planet formation.
