论文摘要
我们介绍了针对Helfer {\ it等}中相等质量紧凑型二进制的治愈性初始数据构建的概括（2019Phys。Rev。D 99 044046; 2022class。tastumgrav。39074001）to to intionaly Massios。我们证明了这些改进的初始数据如何避免在不平等质量玻色子星星二进制二进制的碰撞动力学中以与以前相同的方法相同的方式使用更简单的方法限制在等于质量的情况下。我们采用了改进的初始数据来详细探讨相等和不平等质量玻色子星星二进制的相结合中相位偏移的影响。
We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer {\it et al} (2019 Phys. Rev. D 99 044046; 2022 Class. Quantum Grav. 39 074001) to arbitrary mass ratios. We demonstrate how these improved initial data avoid substantial spurious artifacts in the collision dynamics of unequal-mass boson-star binaries in the same way as has previously been achieved with the simpler method restricted to the equal-mass case. We employ the improved initial data to explore in detail the impact of phase offsets in the coalescence of equal- and unequal-mass boson star binaries.
