Zero Temperature, Degenerate Fermion Stars
S. Boatto, M. B. Paranjape, V. Pessanha +1
We study a zero temperature, degenerate, fermion gas with fermions of rest mass , that only interacts with itself, gravitationally. We describe a self-consistent novel approach…
Field quantization in rotating frames: coordinate covariance and the circular-detector response
Sidney Natzuka Junior, Carlos Augusto Domingues Zarro, Matheus dos Santos Soares
We provide a unified analysis of scalar-field quantization and detector response in relativistic rotating frames, comparing rigid and Trocheris-Takeno (TT) descriptions in unbounde…
Bounds on the photon mass via the Shapiro effect in the solar system
P. C. Malta, C. A. D. Zarro
We study the effects of a finite mass for the photon on its propagation in a weak gravitational field. In particular, we analyse the gravitational time delay, also known as the Sha…
Multiplicative Noise in Euclidean Schwarzschild Manifold
M. S. Soares, N. F. Svaiter, C. A. D. Zarro
We discuss a scalar field model defined in the Euclidean section of the Schwarzschild solution of the Einstein equations in the presence of multiplicative noise. Th…
Noncommutative effects in astrophysical objects: a survey
Orfeu Bertolami, Carlos A. D. Zarro
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}…
Towards a Noncommutative Astrophysics
Orfeu Bertolami, Carlos A. D. Zarro
We consider astrophysical objects such as main-sequence stars, white-dwarfs and neutron stars in a noncommutative context. Noncommutativity is implemented via a deformed dispersion…
