Nahomi Kan, Kiyoshi Shiraishi (Yamaguchi University)
TL;DR
This paper explores how extra dimensions influence the structure and physical properties of degenerate fermion stars, revealing the emergence of Kaluza-Klein modes and layered configurations.
Contribution
It introduces a model of fermion stars with extra dimensions, analyzing the effects of Kaluza-Klein modes and layered structures on their characteristics.
Findings
Kaluza-Klein modes appear for larger extra dimensions
Multiple layers can form inside the stars due to extra dimensions
Extra dimensions significantly alter physical quantities of the stars
Abstract
Many efforts have been devoted to the studies of the phenomenology in particle physics with extra dimensions. We propose degenerate fermion stars with extra dimensions and study what features characterized by the size of extra dimensions should appear in its structure. We find that Kaluza-Klein excited modes arise for the larger scale of extra dimensions and examine the conditions on which different layers should be caused in the inside of the stars. We expound how the extra dimensions affect on physical quantities.
