强子-夸克反应区的结构

The Structure of the Hadron-Quark Reaction Zone

Amir Ouyed, Rachid Ouyed, Prashanth Jaikumar

摘要:

致密物质中的强子-夸克燃烧是致密星位相及其高能天体物理研究的中心课题。我们批判性地回顾了强子夸克燃烧的文献,将它们分为“第一波”,把问题作为一个稳态燃烧或没有机械平衡的约束,和“第二波”,使用数值技术来解决燃烧前,并解决了基本的偏微分方程的化学燃烧前的限制条件较少。我们详细介绍了第二波修正了第一波的不准确之处,并强调了第二波中各种方法之间的关键差异。我们还包括从随时间变化的模拟的反应区,包括强子EOS,中微子,自洽热力学,而不使用参数化的快捷方式的结果。

英文摘要:

Hadron-quark combustion in dense matter is a central topic in the study of phases in compact stars and their high-energy astrophysics. We critically review the literature on hadron-quark combustion, dividing them into a "first wave" that treats the problem as a steady-state burning with or without constraints of mechanical equilibrium, and a "second wave" which uses numerical techniques to resolve the burning front and solves the underlying Partial Differential Equations for the chemistry of the burning front under less restrictive conditions. We detail the inaccuracies that the second wave amends over the first wave, and highlight crucial differences between various approaches in the second wave. We also include results from time-dependent simulations of the reaction zone that include a hadronic EOS, neutrinos, and self-consistent thermodynamics without using parameterized shortcuts.
