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…
