Ultra-Dense Neutron Star Matter, Strange Quark Stars, and the Nuclear Equation of State
Fridolin Weber, Matthew Meixner, Rodrigo P. Negreiros +1
With central densities way above the density of atomic nuclei, neutron stars contain matter in one of the densest forms found in the universe. Depending of the density reached in t…
Is there an enhancement of muons at sea level from transient events?
C. E. Navia, C. R. A. Augusto, M. B. Robba +2
In a recent study of a search for enhancements from the galactic center with muons at sea level using the TUPI muon telescope, we have found several ground level enhancements (GLEs…
General relativistic effects of strong magnetic fields on the gravitational force: a driving engine for bursts of gamma rays in SGRs?
Manuel Malheiro, Subharthi Ray, Herman J. M. Cuesta +1
In general relativity all forms of energy contribute to gravity and not only just ordinary matter as in Newtonian Physics. This fact can be seen in the modified hydrostatic equilib…
Charged Polytropic Stars and a Generalization of Lane-Emden Equation
Rodrigo Picanco, Manuel Malheiro, Subharthi Ray
In this paper we will discuss charged stars with polytropic equation of state, where we will try to derive an equation analogous to the Lane-Emden equation. We will assume that the…
Electrically charged compact stars and formation of charged black holes
Subharthi Ray, Aquino L. Espindola, Manuel Malheiro +2
We study the effect of electric charge in compact stars assuming that the charge distribution is proportional to the mass density. The pressure and the density of the matter inside…
