论文摘要
我们搜索并没有发现Pulsar J1124-5916祖先的较高的质量(> 3msun)未结合的二进制恒星伴侣。有较低的群众候选人,但它们都具有很高的误报概率。现在没有候选人是一个完全没有结合的三重系统。即使一个较低的群众候选人是一个无限的伴侣,似乎不太可能有助于在超新星之前剥夺祖细胞。恒星的质量太低,无法成为显着的质量增加,并且它们的运动太慢,无法成为紧凑的,后常见的包络二进制的幸存者。另外一个系统的添加稍微改善了对超新星祖细胞在死亡前后的二元状态和三重状态的统计限制。
We searched for and found no higher mass (>3Msun) unbound binary stellar companions to the progenitor of pulsar J1124-5916. There are lower mass candidates, but they all have high probabilities of being false positives. There are no candidates for it now being a fully unbound triple system. Even if one of the lower mass candidates is an unbound companion, it seems unlikely that it could have contributed to stripping the progenitor prior to the supernova. The stars are too low mass to be significant mass gainers, and they are too slowly moving to be the survivors of a compact, post-common envelope binary. The addition of one more system slightly improves the statistical constraints on the binary and triple status of supernova progenitors just before and after death.
