Acceptability Conditions and Relativistic Anisotropic Generalized Polytropes
Daniel Suárez-Urango, J. Ospino, Héctor Hernández +1
This paper explored the physical acceptability conditions for anisotropic matter configurations in General Relativity. The study considered a generalized polytropic equation of sta…
Radiating jump conditions in General Relativity
L. F Castañeda-Godoy, J. Ospino, L. A. Núñez
We present a unified description of spherical discontinuity surfaces in General Relativity based on two parameters: mass function and surface permeability. The surfaces considered…
Relativistic Anisotropic Polytropic Spheres: Physical Acceptability
D. Suárez-Urango, L. A. Núñez, H. Hernández
In this work we evaluate the physical acceptability of relativistic anisotropic spheres modeled by two polytropic equations of state -- with the same newtonian limit -- commonly us…
Physical acceptability conditions for realistic neutron star equations of state
D. Ramos-Salamanca, L. A. Núñez, J. Ospino
We select 37 most common and realistic dense matter equation of states to integrate the general relativistic stellar structure equations for static spherically symmetric matter con…
Acceptability Conditions and Relativistic Barotropic Equations of State
Héctor Hernández, Daniel Suárez-Urango, Luis A. Núñez
We sketch an algorithm to generate exact anisotropic solutions starting from a barotropic EoS and setting an ansatz on the metric functions. To illustrate the method, we use a gene…
Cracking in charged relativistic spheres
Guillermo A. González, Anamaría Navarro, Luis A. Núñez
Using the concept of cracking, we have explored the influence of density fluctuations on isotropic and anisotropic charged matter configurations in General Relativity with "barotro…
Plausible families of compact objects with a Non Local Equation of State
H. Hernández, L. A. Núñez
We investigate the plausibility of some models emerging from an algorithm devised to generate a one-parameter family of interior solutions for the Einstein equations. It is explore…
