论文摘要
尽管它在紧凑的星形物理学中具有关键作用，但夸克物质的表面张力尚未得到很好的理解。在这项工作中，我们分析了冷脱裂磁铁的外部和内部核心的三种夸克物质表面张力的行为，生于核心塌陷超新星中的原始磁铁以及在二进制中子星星合并中产生的热磁铁。我们探讨了多个反射膨胀形式主义中温度，巴里昂数量密度，中微子，液滴大小和磁场的作用。夸克物质在MIT袋模型中描述，并被认为在弱相互作用下处于化学平衡状态。我们讨论结果的一些天体物理后果。
In spite of its key role in compact star physics, the surface tension of quark matter is not well comprehended yet. In this work we analyze the behavior of the surface tension of three-flavor quark matter in the outer and inner core of cold deleptonized magnetars, proto magnetars born in core collapse supernovae, and hot magnetars produced in binary neutron stars mergers. We explore the role of temperature, baryon number density, trapped neutrinos, droplet size, and magnetic fields within the multiple reflection expansion formalism. Quark matter is described within the MIT bag model and is assumed to be in chemical equilibrium under weak interactions. We discuss some astrophysical consequences of our results.
