论文摘要
在本文中，我们探讨了孤立的夸克恒星的冷却。这些对象是由均匀的夸克物质核心构成的，并由物质结构。为此，我们采用了两种外壳：（i）在Baym-Pethick-Sutherland（BPS）的状态方程（EOS）和（ii）（II）由奇怪的Quark Matters（strangelets）制成的外壳。这两种模型的模型EOS都具有相同的夸克物质核心。我们的主要目的是量化士兵地壳对这些奇怪恒星的冷却和放松时间的影响。我们还对夸克恒星的热弛豫进行了彻底的研究，在其中，我们发现具有固定果皮的物体具有明显不同的热弛豫时间。我们的研究还包括夸克芯中颜色超导性的可能影响。
In this article, we explore the cooling of isolated quark stars. These objects are structured of a homogeneous quark matter core and crusted by matter. To do this, we adopt two kinds of crust: (i) a crust made of purely nuclear matter following the Baym-Pethick-Sutherland (BPS) equation of state (EoS) and (ii) a crust made of nuggets of strange quark matter (strangelets). Both models have the same quark matter core described by the MIT bag model EoS. Our main purpose is to quantify the effects of a strangelet crust on the cooling and relaxation times of these strange stars. We also perform a thorough study of the thermal relaxation of quark stars, in which we have found that objects with a strangelet crust have a significantly different thermal relaxation time. Our study also includes the possible effects of color superconductivity in the quark core.
