AI 中文摘要
奇异夸克物质是天体物理学中最极端的致密态之一，可以通过相对论致密天体进行探索。由致密奇异夸克物质构成的假想相对论恒星，其特征由该物质的物态方程决定。奇异夸克星的自发标量化受到奇异夸克物质物态方程的影响。在此，我们研究奇异夸克物质的物态方程如何影响这些恒星的自发标量化。在袋模型中考虑正常、色味锁定（CFL）和CFLm夸克物质，并应用标量-张量引力，我们计算了标量化奇异夸克星的结构。我们研究了有效袋常数、微扰QCD参数、CFL配对能隙以及奇异夸克质量如何控制质量-半径关系、中心标量场、标量化阈值和标量荷。我们的结果表明，标量-张量引力中的奇异夸克星是可行的、可检验的天体，它们为利用当前和未来的多信使观测来约束引力理论和冷夸克物质性质建立了一个完整的框架。
英文摘要
Strange quark matter, as one of the most extreme dense states in astrophysics, can be explored through relativistic compact objects. Hypothetical relativistic stars composed of dense strange quark matter are characterized by the equation of state of that matter. The spontaneous scalarization of strange quark stars is influenced by the equation of state of strange quark matter. Here, we investigate how the equation of state of strange quark matter influences the spontaneous scalarization of these stars. Considering Normal, color-flavor-locked (CFL), and CFLm quark matter in the bag models and applying the scalar-tensor gravity, we calculate the structure of scalarized strange quark stars. We investigate how the effective bag constant, perturbative QCD parameter, CFL pairing gap, and strange quark mass control the mass-radius relation, the central scalar field, the scalarization thresholds, and the scalar charge. Our results demonstrate that strange quark stars in scalar-tensor gravity are viable, testable objects, and they establish a complete framework for constraining both the gravitational theory and the properties of cold quark matter with current and future multimessenger observations.
