大自耦合多标量玻色子星的牛顿分析

A Newtonian Analysis of Multi-scalar Boson Stars with Large Self-couplings

Nahomi Kan, Kiyoshi Shiraishi

摘要:

本文研究具有整体对称性的多标量场理论$[U(1)]^N$中玻色子星的解.在大耦合极限的牛顿近似下,研究了玻色子星的性质。我们的目的是研究产生奇异质量分布的模型,以解释星系的平坦自转曲线。我们提出了合理的模型,其中耦合矩阵与图论中的各种图相关联。

英文摘要:

We study solutions for boson stars in the multi-scalar field theory with global symmetry $[U(1)]^N$. The properties of the boson stars are investigated by the Newtonian approximation with the large coupling limit. Our purpose is to study the models bringing about exotic mass distributions which explain flat rotation curves of galaxies. We propose plausible models in which coupling matrices are associated with various graphs in graph theory.
