许多，可能是大多数，恒星形成于双星系统和更高阶的多重系统中。因此，双星系统的性质和频率为恒星形成过程提供了强有力的线索，并限制了恒星形成模型。然而，大多数恒星也形成在星星星团中，其中诞生的双星性质和频率可以通过动力学处理迅速改变。因此，我们几乎看不到出生人口，这使得我们很难知道星星的形成（至少是双星的形成）是否是普遍的，或者它是否取决于环境。此外，外地人口由来自不同集群的系统混合组成，这些系统都以不同的方式处理。
Many, possibly most, stars form in binary and higher order multiple systems. Therefore, the properties and frequency of binary systems provide strong clues to the star-formation process, and constraints on star-formation models. However, the majority of stars also form in star clusters in which the birth binary properties and frequency can be altered rapidly by dynamical processing. Thus, we almost never see the birth population, which makes it very difficult to know whether star formation (as traced by binaries, at least) is universal or whether it depends on the environment. In addition, the field population consists of a mixture of systems from different clusters that have all been processed in different ways.
