摘要

白矮星是质量不足以成为超新星的恒星的残余物。这篇综述探讨了奇异矮星的概念,奇异矮星是一类独特的白矮星,含有奇异夸克物质的核心。与白矮星相比,奇异矮星具有不同的大小、质量和演化路径。它们可能是由奇异夸克星上的正常物质堆积而成,也可能是由奇异子捕获而成。关于奇异矮星的稳定性一直存在争议,最初的研究表明奇异矮星是稳定的,而后来的分析则表明奇异矮星可能是不稳定的。这篇综述重温了这些讨论,重点关注核物质和夸克物质之间的边界条件在决定稳定性方面的关键作用。它还对它们的形成、结构以及在宇宙中的可能探测提供了见解。

Strange Dwarfs: A Review on the (in)Stability
White dwarfs are the remnants of stars not massive enough to become supernovae. This review explores the concept of strange dwarfs, a unique class of white dwarfs that contain cores of strange quark matter. Strange dwarfs have different sizes, masses, and evolutionary paths with respect to white dwarfs. They might form through the accumulation of normal matter on strange quark stars or by the capture of strangelets. The stability of strange dwarfs has been debated, with initial studies suggesting stability, while later analyses indicated potential instability. This review revisits these discussions, focusing on the critical role of boundary conditions between nuclear and quark matter in determining stability. It also offers insights into their formation, structure, and possible detection in the universe.
