Axially symmetric ghost stars
L. Herrera, J. L. Hernandez-Pastora, J. Ospino +1
We present static axially symmetric fluid distributions not producing gravitational field outside their boundaries (i.e. fluid sources which match smoothly on the boundary surface…
A Methodological Framework for Solving Einsteins Equations in Axially Symmetric Spacetimes
J. Ospino, J. L. Hernández-Pastora, A. V. Araujo-Salcedo +1
This work presents a novel methodology for deriving stationary and axially symmetric solutions to Einstein field equations using the 1+3 tetrad formalism. This approach reformulate…
Expansion-free dissipative fluid spheres: Analytical models
L. Herrera, A. Di Prisco, J. Ospino
We search exact analytical solutions of spherically symmetric dissipative fluid distributions satisfying the vanishing expansion condition (vanishing expansion scalar ). To do s…
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…
Dynamics of hyperbolically symmetric fluids
L. Herrera, A. Di Prisco, J. Ospino
We study the general properties of dissipative fluid distributions endowed with hyperbolical symmetry. Their physical properties are analyzed in detail. It is shown that the energy…
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…
