论文摘要
当以二进制形成一个紧凑的物体时，核心崩溃期间损失的任何质量都会在二进制的质量中心踢。这种质量损失或中微子发射中的不对称性将在残留的黑洞或中子星上额外踢出一个额外的鼻踢，无论是在二进制中还是孤立地形成。尽管中子恒星在编队时得到了出生的踢球，但尚不清楚黑洞是否也可以做到。在这里，我们考虑了低质量X射线二进制二进制Maxi J1305-704，据报道，该X射线Maxi J1305-704具有空间速度$ \ gtrsim $ 200 km/s。除了整合其轨迹以在形成黑洞后推断其速度外，我们还考虑了其周期，黑洞质量，质量比和供体有效温度的估计值，从光度和光谱观测中进行有效温度。我们发现，如果Maxi J1305-704是通过厚的银河磁盘中孤立的二进制进化形成的，那么形成其黑洞的超新星会散发出至少70 km/s的出现踢球，而弹出少于$ \ \\ simeq 1 $ m $ _ \ odot $ _ \ odot $ $ _ \ odot $ witter nof Fustry $ witter 95％的自信差不多是在弥撒损失的范围和nat ant ant ant ant ant nat and nat ant nat。
When a compact object is formed in a binary, any mass lost during core collapse will impart a kick on the binary's center of mass. Asymmetries in this mass loss or neutrino emission would impart an additional natal kick on the remnant black hole or neutron star, whether it was formed in a binary or in isolation. While it is well established that neutron stars receive natal kicks upon formation, it is unclear whether black holes do as well. Here, we consider the low-mass X-ray binary MAXI J1305-704, which has been reported to have a space velocity $\gtrsim$ 200 km/s. In addition to integrating its trajectory to infer its velocity upon formation of its black hole, we account for recent estimates of its period, black hole mass, mass ratio, and donor effective temperature from photometric and spectroscopic observations. We find that if MAXI J1305-704 formed via isolated binary evolution in the thick Galactic disk, then the supernova that formed its black hole imparted a natal kick of at least 70 km/s while ejecting less than $\simeq 1$ M$_\odot$ with 95% confidence assuming uninformative priors on mass loss and natal kick velocity.
