En este trabajo se muestra que es posible obtener modelos físicamente aceptables para configuraciones de materia ultradensa, con simetría esférica, los cuales satisfacen una ecuación de estado no local. Este tipo particular ...

Sound speeds, cracking and stability of self-gravitating anisotropic compact objects. Abstract Using the the concept of cracking we explore the influence of density fluctuations and local anisotropy have on the stability ...

Cracking of self-gravitating compact objects with local and non local equations of state. (Abreu, Henso; Hernández, Hector y Núñez, Luis) Abstract We discuss the effect that small fluctuations of density and local ...

Nonlocal equation of state in general relativistic radiating spheres (Núñez, Luis; Hernández, Hector; Percoco, Umberto) Abstract We show that under particular circumstances a general relativistic spherically symmetric ...

Nonlocal equation of state in anisotropic static fluid spheres in general relativity (Núñez, Luis; Hernández, Hector) Abstract We show that it is possible to obtain credible static anisotropic spherically symmetric ...

On the eccentricity behaviour of radiating slowly rotating bodies (Núñez, Luis; Hernández, Hector; Herrera, Luis; Percoco, Umberto) Abstract We study different models of radiating slowly rotating bodies up to the ...

Static anisotropic solutions to Einstein equations with a nonlocal equation of state (Núñez, Luis; Hernández, Hector) Abstract We present a general method to obtain static anisotropic spherically symmetric solutions, ...
