All analytic solutions for geodesic motion in axially symmetric space-times
J. Ospino, J. L. Hernandez-Pastora, L. A. Nunez
Recent observations of the orbits of star clusters around Sgr , imaging of black holes and gravitational waveforms of merging compact objects require a detailed understand…
Convection and cracking stability of spheres in General Relativity
Héctor Hernández, Luis A. Núñez, Adriana Vásquez-Ramírez
In the present paper we consider convection and cracking instabilities as well as their interplay. We develop a simple criterion to identify equations of state unstable to convecti…
Cracking isotropic and anisotropic relativistic spheres
Guillermo A. Gonzalez, Anamaria Navarro, Luis A. Nunez
We explore the influence of density fluctuations on isotropic and anisotropic configurations, extending the concept of cracking for general relativistic fluid spheres. This concept…
Quasi-static thermal evolution of compact objects
L. Becerra, H. Hernandez, L. A. Nunez
We study under what conditions the thermal peeling is present for dissipative local and quasi-local anisotropic spherical matter configurations. The thermal peeling occurs when dif…
Sound Speeds, Cracking and Stability of Self-Gravitating Anisotropic Compact Objects
H. Abreu, H. Hernandez, L. A. Nunez
Using the the concept of cracking we explore the influence of density fluctuations and local anisotropy have on the stability of local and non-local anisotropic matter configuratio…
Hydrodynamics in Class B Warped Spacetimes
J. Carot, L. A. Nunez
We discuss certain general features of type B warped spacetimes which have important consequences on the material content they may admit and its associated dynamics. We show that,…
