关于恒星的形成，IMF到底告诉了我们什么？
What does the IMF really tell us about star formation?
摘要：
获得初始质量函数（IMF）的精确测量通常被认为是理解恒星形成的关键，而普遍的IMF通常被认为意味着普遍的恒星形成过程。在这里，我们说明了不同的恒星形成模式可以导致相同的IMF，为了真正了解恒星的形成，有必要更深入地了解原始双星的人口。详细的知识的二进制分数，质量比分布，和其他二进制参数，作为质量的函数，是恢复恒星形成过程的恒星星族测量的要求。
英文摘要：
Obtaining accurate measurements of the initial mass function (IMF) is often considered to be the key to understanding star formation, and a universal IMF is often assumed to imply a universal star formation process. Here, we illustrate that different modes of star formation can result in the same IMF, and that, in order to truly understand star formation, a deeper understanding of the primordial binary population is necessary. Detailed knowledge on the binary fraction, mass ratio distribution, and other binary parameters, as a function of mass, is a requirement for recovering the star formation process from stellar population measurements.
