摘要

本研究主要侧重于在扩展对称远平行引力框架内探索各向异性球的性质。为此，我们考虑了 f ( Q , T ) $f(Q,T)$引力模型与 Tolman-Kuchowicz 时空的各向异性物质分布。通过分析，讨论了球体内部和外部几何形状匹配的必要条件，并计算了相关未知参数的值。此外，还利用紧凑天体的观测数据分析了这些球体的物理特性。结果表明，各向异性球体的内部解符合所有必要的物理标准，从而确保了我们模型的稳定性。

Anisotropic Spheres with Tolman–Kuchowicz Spacetime in the Context of f ( Q , T ) $f(Q,T)$ Gravity

This study primarily focuses on exploring the nature of anisotropic spheres within the framework of extended symmetric teleparallel gravity. To accomplish this, an anisotropic matter distribution for $f (Q, T)$ gravity model with Tolman–Kuchowicz spacetime is considered. Through this analysis, the necessary conditions for matching the interior and exterior geometries of the spheres are discussed and calculated the values of the unknown parameters involved. Furthermore, the physical properties of these spheres are analyzed using observational data from compact objects. The results demonstrate that the interior solutions obtained for anisotropic spheres fulfill all requisite physical criteria, thereby ensuring the stability of our model.

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
