我们比较的梅萨恒星演化代码中的COSMIC人口合成代码中的演化的二进制系统。我们的目标是传达的稳健性方程模型二进制演化的COSMIC代码，特别是对于高质量的恒星与紧密的轨道紧凑的对象同伴的情况下。我们更大的目标是准确地模拟这些系统的速率，因为它们是充满活力的，持久的，射电明亮的伽玛射线暴喷流背后的祖先系统的有希望的候选者。这些系统也可能是整个宇宙中二元黑洞合并速率的关键贡献者。
We compare the evolution of binary systems evolved in the MESA stellar evolution code to those in the COSMIC population synthesis code. Our aim is to convey the robustness of the equations that model binary evolution in the COSMIC code, particularly for the cases of high mass stars with closely orbiting compact object companions. Our larger goal is to accurately model the rates of these systems, as they are promising candidates for the progenitor systems behind energetic, longer lasting, radio bright GRB jets. These systems also may be key contributors to the rates of binary black hole mergers throughout our Universe.
