Stability of hybrid stars via catastrophe theory
Eduardo S. Fraga, Sergio E. Jorás
We discuss the possible topologies of the mass-radius relation for hybrid stars in light of catastrophe theory. We show that different branches of compact stars emerge or disappear…
Covariant Tolman-Oppenheimer-Volkoff equations in Energy-Momentum Squared Gravity
Eduardo Bittencourt, Mariam Campbell, Peter K. S. Dunsby +1
We study static, spherically symmetric stellar configurations in an extended class of Energy--Momentum Squared Gravity using the covariant \(1+1+2\) semi-tetrad formalism. For perf…
Covariant Dynamical Systems Formulation of the Tolman-Oppenheimer-Volkoff Equations
Eduardo Bittencourt, Mariam Campbell, Peter K. S. Dunsby +1
We revisit static, spherically symmetric perfect-fluid stellar models in General Relativity within the framework of the semi-tetrad formalism. For locally rotationally symm…
