K场论中的紧致玻色子星

Compact boson stars in K field theories

C. Adam, N. Grandi, P. Klimas, J. Sanchez-Guillen, A. Wereszczynski

摘要:

本文研究了一个非标准动力学项与引力最小耦合的标量场理论。我们建立了紧玻色子星的存在性,即在考虑自引力的情况下,完整系统的紧支撑的静态解。具体地说,存在两种类型的解决方案,即一方面是紧球,另一方面是紧壳。致密球的中心有一个裸奇点。紧壳的内边界也是奇异的,但它同时是一个Killing视界。因此,这些奇异的致密壳层类似于黑洞。

英文摘要:

We study a scalar field theory with a non-standard kinetic term minimally coupled to gravity. We establish the existence of compact boson stars, that is, static solutions with compact support of the full system with self-gravitation taken into account. Concretely, there exist two types of solutions, namely compact balls on the one hand, and compact shells on the other hand. The compact balls have a naked singularity at the center. The inner boundary of the compact shells is singular, as well, but it is, at the same time, a Killing horizon. These singular, compact shells therefore resemble black holes.
