Noncommutative effects in astrophysical objects: a survey

General Relativity and Quantum Cosmology 2015-05-18 v1

Abstract

The main implications of noncommutativity over astrophysical objects are examined. Noncommutativity is introduced through a deformed dispersion relation E2=p2c2(1+λE)2+m2c4E^{2}=p^{2}c^{2}(1+\lambda E)^{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.
