不同总质量旋转母气结构的双星系统比较
Comparing binary systems from rotating parent gas structures with different total masses
摘要：
在本文中，我们继续调查报告的\cite{RMAA}关于通过崩溃的总质量范围为M $_T$ = 1至5 M $_{\odot}$的旋转母气体结构的二元配置的形态。在这里，我们扩大质量范围，并考虑崩溃的两个均匀的气体团的M $_T$ = 50和400 M $_{\odot}$，使他们也刚性旋转，以这样一种方式，其近似维里参数采取的值为0.5，1.5，和2.5和他们的崩溃是诱导最初通过实施方位角质量扰动。为了评估母气结构的总质量对所产生的二元结构的性质的影响，我们还考虑了两个核心的M $_T$ = 1和5 M $_{\odot}$的崩溃。我们计算的所有这些母气结构的崩溃，使用三个值的热能势能的比率和两个值的质量扰动幅度。接下来，我们计算二元分离，质量和二元碎片的积分性质，并将它们以母体结构的总质量表示。对于我们的大多数模型，我们最终计算$β$极值，这样具有稍高$β$值的模型将不再崩溃。
英文摘要：
In this paper we continue the investigation reported by \cite{RMAA} concerning the morphology of binary configurations obtained via the collapse of rotating parent gas structures with total masses in the range of M$_T$= 1 to 5 M$_{\odot}$. Here we extend the mass range and consider the collapse of two uniform gas clumps of M$_T$= 50 and 400 M$_{\odot}$, so that they also rotates rigidly in such a way that its approximate virial parameter takes the values of 0.5, 1.5, and 2.5 and their collapse is induced initially by implementing an azimuthal mass perturbation. To assess the effects of the total mass of the parent gas structure on the nature of the resulting binary configurations, we also consider the collapse of two cores of M$_T$= 1 and 5 M$_{\odot}$. We calculate the collapse of all these parent gas structures using three values of the ratio of thermal energy to potential energy and for two values of the mass perturbation amplitude. We next calculate the binary separations, masses and integral properties of the binary fragments and present them in terms of the total mass of the parent structure. For most of our models, we finally calculate the $β$ extreme value, so that a model with a slightly higher $β$ value would no longer collapse.
