天体物理中的非对易效应:综述

Noncommutative effects in astrophysical objects: a survey

Orfeu Bertolami, Carlos A. D. Zarro

摘要:

主要的影响,非对易性的天体物理对象进行检查。通过变形色散关系$E^{2}=p^{2}c^{2}(1+λE)^{2} + m^{2}c^{4}$引入非对易性,并利用巨正则系综计算了相关的物理量.这些结果被应用到描述主序星、白矮星和中子星的简单物理模型中。讨论了主序星和白矮星的稳定性。

英文摘要:

The main implications of noncommutativity over astrophysical objects are examined. Noncommutativity is introduced through a deformed dispersion relation $E^{2}=p^{2}c^{2}(1+λE)^{2} + m^{2}c^{4}$ and the relevant thermodynamical quantities are calculated using the grand canonical ensemble formalism. These results are applied to simple physical models describing main-sequence stars, white-dwarfs and neutron stars. The stability of main-sequence stars and white dwarfs is discussed.
