论文摘要
在这项工作中，我们从GW190814事件的引力波的观察中获取提示，这表明信号的来源可以归因于紧凑型二元合并为22.2至24.3 $ m _ {\ odot} $ black Hole} $ Black Hole和2.50至2.50至2.67 $ m m _ _ _ _ _ _ _ __________________________________________________ {在当前的博览会中，我们关注聚结对的较低质量成分的建模。我们利用$ f（\ Mathcal {Q}）$重力以及最小几何变形（MGD）技术来获得与GW190814事件对齐的质量的紧凑型恒星对象。从Tolman IV ANSATZ开始用于其中一个度量函数的ANSATZ，以及MIT袋模型方程式，我们能够减少完全描述种子溶液的重力行为的问题。通过MGD技术，我们通过变形引力电位的径向部分来引入各向异性。这使我们能够获得两个新的解决方案，这些解决方案取决于度量参数，$ \ cal q $和变形常数，$β$。我们表明，这两个参数在确定模型的热力学行为和稳定性中起着至关重要的作用。特别是，我们表明，度量参数与变形常数之间的相互作用导致预测的祖细胞表达为GW190814的二级成分。
In this work we take our cue from the observations of gravitational waves of the GW190814 event which suggests that source of the signals can be ascribed to a compact binary coalescence of a 22.2 to 24.3$ M_{\odot}$ black hole and a compact object endowed with a mass of 2.50 to 2.67$M_{\odot}$. In the current exposition, we are concerned with modeling of the lower mass component of the coalescence pair. We utilise the $f(\mathcal{Q})$ gravity together with Minimum Geometric Deformation (MGD) technique to obtain compact stellar objects with masses aligned with the GW190814 event. Starting off with the Tolman IV ansatz for one of the metric functions, together with a MIT Bag model equation of state we are able to reduce the problem of fully describing the gravitational behaviour of the seed solution to a quadrature. Through the MGD technique, we introduce anisotropy by deforming the radial part of the gravitational potential. This enables us to obtain two new classes of solutions which depend on the metricity parameter, $\cal Q$ and the deformation constant, $β$. We show that these two parameters play a crucial role in determining the thermodynamical behaviour and stability of our models. In particular, we show that the interplay between the metricity parameter and the deformation constant leads to predicted mass of the progenitor articulating as the secondary component of GW190814.
